[SunHELP] Core dumped in _malloc_unlocked and realloc on Solaris 8

Mon Dec 3 04:10:21 CST 2001

Hi all,

I am new in this list and I hope that here people which had similar
problems as me and give me an advice.

I working on application which uses CORBA. One particular server-side
multithreaded program core dumps in call malloc. I use GCC-2.95.2 from
www.sunfreeware.com. I think that this bug is solved for Sun C 5.0
compiler, but not for GCC. Do anybody know what I do wrong?

It runs on system Sun ULTRA 5 and on Fujitsu-Siemens M800. This systems
use same version of operating environment.
$ uname -a
SunOS berta 5.8 Generic sun4u sparc SUNW,Ultra-5_10

Thank you for advice, Libor Chocholaty

Here is a backtrace from my core dump:
