#5 Memory corruption

[Anonymous]

Hi there,

so, I am trying to build an network simulator using
parasol on Kubuntu 5.1 i386 gcc 4.02 1Gb Ram amd dual
core 3800+. I use valgrind for inspecting memory
problems. Well parasol seems to mess up my program. The
same occurs when I run the synchro example. I run
valgrind with like this:
"valgrind --log-file=LOG -v --max-stackframe=922117100
--leak-check=yes --show-reachable=yes --error-limit=no
synchro"

and errors are (some of them)

I did not compile parasol and synchro with debug info
and optimization.

Any ideas?
