Many tests of Boost v1.54 fail

[Tony Reix]

I'm now testing Boost v1.54 from Ubuntu sources.

I've done:

sudo apt-get update
sudo apt-get install libboost-dev
sudo apt-get install libboost-all-dev
sudo apt-get install dpkg-dev
sudo apt-get build-dep boost1.54
     apt-get source boost1.54
sudo apt-get build-dep boost1.54
cd boost1.54-1.54.0
sudo dpkg-buildpackage
cd status
../b2 2>&1 | tee ../../b2.TestAll.1.log

and I've got the following errors:

Looping : ../bin.v2/libs/flyweight/test/test_intermod_holder.test/gcc-4.8/debug/threading-multi/test_intermod_holder

Tests were blocked due to "test_intermod_holder" looping infinitely. I have to run the tests after this blocking test.

Results were compared to Boost results on page: http://beta.boost.org/development/tests/master/developer/summary.html .
Though some tests do fail on x86 platform, many tests should succeed and, for sure, should not core or run in an infinite loop.

So, these errors should be investigated and fixed.
First try to understand a core goes into libs C and C++.

About version 1.55, I also have many failures (test failed, core, infinite loop, plus bad memory access).

[Tony Reix (tony-reix)]

After debugging "some" more, it looks like the issue is in:

BOOST : libs/filesystem/src/path.cpp

  std::locale path::imbue(const std::locale& loc)
  {
    std::locale temp(path_locale); <<<<<<<<<<<<<<<<<<<<<<< line 918
    path_locale = loc;
    codecvt_facet_ptr =
      &std::use_facet<std::codecvt<wchar_t, char, std::mbstate_t> >(path_locale);
    return temp;
  }

At line 918, C++ try to do some initialization. This seems to imply to use field _M_impl of path_locale, which is 0x0.
It seems that no initialization of path_locale is done and thus _M_impl stay 0x0.

p path_locale
$23 = {static none = 0, static ctype = 1, static numeric = 2, static collate = 4, static time = 8, static monetary = 16, static messages = 32, static all = 63, _M_impl = 0x0,
  static _S_classic = 0x3fffb7fae0b8 <(anonymous namespace)::c_locale_impl>, static _S_global = 0x3fffb7fae0b8 <(anonymous namespace)::c_locale_impl>, static _S_categories =
    0x3fffb7f92cb8 <__gnu_cxx::category_names>, static _S_once = 0}

So, the question is: why path_locale has not been initialized ? and why this happens in PPC/LE and not elsewhere ?

Since, at line 868, we have:

 std::locale path_locale; // initialized by path::codecvt() below
  const std::codecvt<wchar_t, char, std::mbstate_t>* codecvt_facet_ptr; // ditto

which does not seems to do any initialization (gdb don't stop there). however, the comment says that path_locale is initialiazed by line below, where gdb does not stop.

Do you have and can provide a list of tests which pass on Ubuntu-amd64 (x86_64) but fail on Ubuntu-ppc64el (ppc/le) for further investigation?

Results as published on boost.org, may not match Ubuntu-amd64 baseline.

[Tony Reix (tony-reix)]

On my PC, running oneiric, version 11.10, on Xeon, with gcc 4.6.1, I also see errors when testing Boost v1.55.
EXIT STATUS are:
      1 : 11 (False results)
134 : 1 (Exception, aborted)
139 : 2 (Seg Fault)
200 : 10 (memory access violation)
201 : 8 (error detected)

I have to find a x86 machine I can install with a fresh Ubuntu. No time for doing that for now, but I'll do.

When comparing what I get on PPC/LE and my PC, about most important errors (seg fault, memory acces, exception aborted), I have:
- Errors on both environments:
   ES 134:

     ../bin.v2/libs/heap/test/priority_queue_test.test/gcc-*/debug/threading-multi/priority_queue_test.output"

- Errors only on PPC/LE :
   ES 134: NONE
   ES 139:
      ../bin.v2/libs/context/test/test_context.test/gcc-4.8/debug/link-static/test_context.output

    ../bin.v2/libs/test/test/prg_exec_fail2.test/gcc-4.8/debug/prg_exec_fail2.output

   ES 200:
     ../bin.v2/libs/heap/test/d_ary_heap_test.test/gcc-4.6.1/debug/threading-multi/d_ary_heap_test.output"

So, there are cores and memory access violations that are specific to PPC/LE.
And there are cores and memory access violations that are common to both environments, though they use different versions of GCC.

I am now building/testing on PPC/BE in order to compare. It uses same version of GCC.

I forgot to talk again about the tests running an infinite loop on PPC64, that never appear on AMD64:

Here are infinite loops on PPC64-BE (I provide the last trace appearing on the screen. The blocking test is: test_tr1* that I killed) :

gcc.link ../bin.v2/libs/math/test/test_tr1.test/gcc-4.8.2/debug/link-static/test_tr1
gcc.link ../bin.v2/libs/math/test/test_tr1_long_double.test/gcc-4.8.2/debug/link-static/test_tr1_long_double
gcc.link ../bin.v2/libs/math/test/test_tr1_c.test/gcc-4.8.2/debug/link-static/test_tr1_c
gcc.link ../bin.v2/libs/math/test/test_tr1_c_long_double.test/gcc-4.8.2/debug/link-static/test_tr1_c_long_double
./bin.v2/libs/math/test/test_bessel_y.test/gcc-4.8.2/debug/link-static/test_bessel_y

Here are infinite loops on PPC64-LE:

gcc.link ../bin.v2/libs/math/test/test_ellint_1.test/gcc-4.8/debug/link-static/test_ellint_1
gcc.link ../bin.v2/libs/math/test/test_ellint_2.test/gcc-4.8/debug/link-static/test_ellint_2
gcc.link ../bin.v2/libs/math/test/test_ellint_2.test/gcc-4.8/debug/link-static/test_ellint_3

Anyway, it also seems that there are MANY tests failures about the Math library on PPC64.

There are few PPC assembler files in Boost (v1.55) :
./libs/context/src/asm/jump_ppc64_sysv_elf_gas.S
./libs/context/src/asm/jump_ppc32_sysv_elf_gas.S
./libs/context/src/asm/make_ppc64_sysv_elf_gas.S
./libs/context/src/asm/make_ppc32_sysv_elf_gas.S

And I've not found any PPC assembler code included in C++ files. Only Intel assembler optimizations.

That means to says that assembler code in Boost should not be the root cause of the issues I've found. Moreover, though there are more issues on Ubuntu PPC64/LE than on Fedora PPC64/BE, there are issues on PPC64/BE, which has a stable ABI compared to the recently changed ABI on PPC64/LE .

Understanding and fixing errors common to both PPC64 BE and LE would help, as a first attempt.

[Peter Bergner (pbergner)]

How does this compare to the test results on BE?

[Tony Reix (tony-reix)]

This is described in comment #12 :
   https://bugs.launchpad.net/ubuntu/+source/boost1.54/+bug/1276262/comments/12
(However, I've just found that core (error 139) on PPC64/LE also appears on AMD64: my mistake).

Boost 1.55 on PPC64 shows more and different issues on LE than on BE. However, same faulty code may generate different errors according to the testing environment.
I'm still investigating. make/jump_ppc32_sysv_elf_gas.S seems to be the root cause for all PPC64 BE & LE cores. Trying to figure out what is the root cause in this assembler code. Maybe some PPC64 fixes were produced but are not available on versions 1.54 and 1.55 of Boost. I'll look at most recent versions of Boost.

[Tony Reix (tony-reix)]

Revision 86799 of :
./libs/context/src/asm/jump_ppc64_sysv_elf_gas.S
./libs/context/src/asm/make_ppc64_sysv_elf_gas.S
is exactly identical to the version delivered with Boost v1.55 .
