I expect a shared library on Mandrake is incompatible with the
corresponding one on RH6.0 (even though that isn't supposed to
happen). Try recompiling. If that doesn't help, then run it under
gdb. I also suggest you look at electric-fence or yamd, which use the
virtual memory hardware to help debug memory access bugs.

Maybe the default max core size is smaller on the Mandrake system.
Check the ulimit command (a bash builtin).
