            Bug ID: 63617
           Summary: Crash in libstdc++ on AIX.
           Product: gcc
           Version: 4.6.3
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org

Hello,

We have a program "myapp" build with gcc 4.6.3 on AIX 6.1 Tl05.

At runtime the program crashed once very weird with the following stack:

pth_signal.pthread_kill(??, ??) at 0xd053c8d4
pth_signal._p_raise(??) at 0xd053bd64
raise.raise(??) at 0xd01209a0

The "Thread::mainF" is a thread routine that was passed to pthread_create.
We consider our code inside this method clean.

Please advise what kind of system call from our side could have generated this
stack. I mean we do not call directly any "bitmap_allocator".

Our program(myapp) has the following dependencies:
bash-4.2# ldd myapp
myapp needs:
         /usr/lib/threads/libc.a(shr.o)
         /usr/lib/libpthread.a(shr_xpg5.o)
         /usr/mypath/libstdc++.a(libstdc++.so.6)
         /usr/mypath/libgcc_s.a(shr.o)
         /usr/lib/libiconv.a(shr4.o)
         /usr/lib/libpthread.a(shr_comm.o)
         /usr/lib/libqb.a(shr.o)
         /unix
         /usr/lib/libcrypt.a(shr.o)
         /usr/lib/libpthreads.a(shr_comm.o)
         /usr/lib/libpthreads_compat.a(shr.o)
         /usr/lib/libz.a(libz.so.1)
         /usr/lib/libpthreads.a(shr.o)
The libstdc++.a and libgcc_s.a are taken from the gcc 4.6.3 compiler.

Thank you !

--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
GCC 4.6 is no longer supported, so unless you can reproduce this with a current
release noone is going to investigate.

I'm assuming you've configured GCC to use the bitmap_allocator as the default
C++ allocator, so one likely cause is that an exception was thrown due to
failure to allocate memory.

In any case, please provide the information requested by

Can you tell me what are the "supported" version(s) now?

Also can you give me a kind of gcc supported version life cycle/chart/roadmap ?

Thank you,
Adi
