Bug Description
Binary package hint: gdb
Asking for an UVF exception for gdb-6.8, upstream changes below, better pie support in updated pie patches.
*** Changes in GDB 6.8
* New native configurations
NetBSD/hppa hppa*-*netbsd*
Xtensa GNU/Linux xtensa*-*-linux*
* New targets
NetBSD/hppa hppa*-*-netbsd*
Xtensa GNU/Lunux xtensa*-*-linux*
* Change in command line behavior -- corefiles vs. process ids.
When the '-p NUMBER' or '--pid NUMBER' options are used, and
attaching to process NUMBER fails, GDB no longer attempts to open a
core file named NUMBER. Attaching to a program using the -c option
is no longer supported. Instead, use the '-p' or '--pid' options.
* GDB can now be built as a native debugger for debugging Windows x86
(mingw32) Portable Executable (PE) programs.
* Pending breakpoints no longer change their number when their address
is resolved.
* GDB now supports breakpoints with multiple locations,
including breakpoints on C++ constructors, inside C++ templates,
and in inlined functions.
* GDB's ability to debug optimized code has been improved. GDB more
accurately identifies function bodies and lexical blocks that occupy
more than one contiguous range of addresses.
* Target descriptions can now describe registers for PowerPC.
* The GDB remote stub, gdbserver, now supports the AltiVec and SPE
registers on PowerPC targets.
* The GDB remote stub, gdbserver, now supports thread debugging on GNU/Linux
targets even when the libthread_db library is not available.
* The GDB remote stub, gdbserver, now supports the new file transfer
commands (remote put, remote get, and remote delete).
* The GDB remote stub, gdbserver, now supports run and attach in
extended-remote mode.
* hppa*64*-*-hpux11* target broken
The debugger is unable to start a program and fails with the following
error: "Error trying to get information about dynamic linker".
The gdb-6.7 release is also affected.
* GDB now supports the --enable-targets= configure option to allow
building a single GDB executable that supports multiple remote
target architectures.
* GDB now supports debugging C and C++ programs which use the
Decimal Floating Point extension. In addition, the PowerPC target
now has a set of pseudo-registers to inspect decimal float values
stored in two consecutive float registers.
* The -break-insert MI command can optionally create pending
breakpoints now.
* Improved support for debugging Ada
Many improvements to the Ada language support have been made. These
include:
- Better support for Ada2005 interface types
- Improved handling of arrays and slices in general
- Better support for Taft-amendment types
- The '{type} ADDRESS' expression is now allowed on the left hand-side
of an assignment
- Improved command completion in Ada
- Several bug fixes
* New commands
set print frame-arguments (all|scalars|none)
show print frame-arguments
The value of this variable can be changed to control which argument
values should be printed by the debugger when displaying a frame.
remote put
remote get
remote delete
Transfer files to and from a remote target, and delete remote files.
* New MI commands
-target-file-put
-target-file-get
-target-file-delete
Transfer files to and from a remote target, and delete remote files.
* New remote packets
vFile:open:
vFile:close:
vFile:pread:
vFile:pwrite:
vFile:unlink:
Open, close, read, write, and delete files on the remote system.
* GDB on GNU/Linux and HP/UX can now debug through "exec" of a new
process.
vAttach
Attach to an existing process on the remote system, in extended-remote
mode.
vRun
Run a new process on the remote system, in extended-remote mode.

Testing looks good -- upstream added more tests, and older tests have fewer failures. Attaching testsuite differences log, which also shows great improvement in the PIE handling (which I confirmed manually as well).
