libstdc++ test failures

[Matthias Klose]

Binary package hint: gcc-4.4

Compared to the Debian build, there are some additional test failures for libstdc++-v3:

 - failures caused by the hardening defaults

 - failures, when the testsuite is run with the installed libstdc++

see the attachment for more details

[Matthias Klose (doko)]

the testsuite-hardening-*.diff patches should be updated

[Kees Cook (kees)]

Stack crash is a real regression (I've opened bug 598670), but it is fixed in 4.5.1 and later already. Updated testsuite-hardening-fortify.diff attached for the freopen issues. Still investigating the assert failures.

I'm not sure what's causing the assert failures.

4.5 has some more:

for the assertion failures,

I don't see the ext/* failues in gcc-linaro-4.5-2010.08-1 on i686, x86_64, or armv7a.

I had a quick look and it seems that ext/* are being included by libstdc++-v3/testsuite/libstdc++-dg/conformance.exp so they're probably running.

[Matthias Klose (doko)]

on amd64, these still fail for -m32:
https://launchpad.net/ubuntu/+source/gcc-4.5/4.5.1-1ubuntu2/+build/1919225

on i386, these fail for the normal build:
https://launchpad.net/ubuntu/+source/gcc-4.5/4.5.1-1ubuntu2/+build/1919227

on armel, the testsuite isn't run on the buildd.

[Matthias Klose (doko)]

fixed for 4.4

[Matthias Klose (doko)]

gcc-4.5 still needs updates

[Matthias Klose (doko)]

removed the patch tag, gcc-4.5 needs updates, and gcc-4.6 did enter stage3

[Matthias Klose (doko)]

won't fix for 4.5
