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

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