abort() and exit(1) make RHEL freeze when core size limit is higher than

Hi all,

I encountered the following problem - when my C++ application executes the abort() or exit(1) system instructions, if the core size limit was previously set to more than ~2MB (ulimit -c 2000), my PC freezes totally and must be power-cycled...

If the core limit is left untouched to 0 (default), the abort or exit instructions are executed without problems, but of course no core file is dumped !

If core limit is set to 2000 or less, a core file is dumped but it is unreadable (certainly because it is trimmed to less than its actual size).

If core limit is set to 4000 or higher (including 'ulimit -c unlimited') the machine freezes as soon as abort() or exit() are executed.

Here are my configuration details :

address@hidden:wielemans] cat /etc/redhat-release
Red Hat Enterprise Linux WS release 3 (Taroon Update 1)

address@hidden:wielemans] uname -a
Linux electro 2.4.21-9.0.1.EL #2 Fri Apr 16 13:51:32 CEST 2004 i686 i686 i386 GNU/Linux

address@hidden:wielemans] gcc -v

If you need more details, please ask ! Any help or idea welcome, thanks in advance...

Have a nice day !

Willy.
