HP-UX11.11: coredump when using lib pthread

[Jose Ribeiro_2]

Hi,

i'm using a program compiled wit aCC A.03.65 with the option -AA, but when it is linked with library pthread (/usr/lib/libpthread.1), the execution aborts with coredump.

The core analysis:
#0 0xc003de84 in pthread_mutex_lock+0x68 () from /usr/lib/libpthread.1
#1 0xc021c438 in __thread_mutex_lock+0x70 () from /usr/lib/libc.2
#2 0xc2f394c4 in _HPMutexWrapper::lock+0x30 () from /usr/lib/libstd_v2.2
#3 0xc2f04b5c in std::locale::_C_install_facet+0x244 () from /usr/lib/libstd_v2.2
#4 0xc2f047b8 in std::locale::_C_make_facet+0x528 () from /usr/lib/libstd_v2.2
#5 0x99048 in std::basic_filebuf>::overflow (this=0x7b01d190, __c=-1)
at /opt/aCC/include_std/fstream.cc:339
#6 0x998b0 in std::basic_filebuf>::sync (this=0x7b01d190) at /opt/aCC/include_std/fstream.cc:572

My question is, it's possible to C++ v2 iostream use (libs CSup_v2 and std_v2) and libpthread.1?

Thanks,
José Ribeiro

Only if you consistently compile with -mt.

[Jose Ribeiro_2]

It must be possible to use libpthread.1, i think, because it's the only one available, don't exist a libpthread_v2...

But Thanks

My comment wasn't about the version of libpthead but the fact that to use libpthread with aC++ requires compiling with -mt:

Recompiling all the code with the -mt option resolved the coredump.

Thanks for the help, it solved my problem.
