Did you compile YICS yourself? If so, what version of gcc
did you use?
Logged In: YES
user_id=581712
Yes I did.
gcc 3.3.3
Logged In: NO
This seems to happen with various versions of gcc, and I'm
not sure why. Somehow a pointer that is not changed by YICS
gets offset by a certain amount, and when YICS goes to free
it, the program explodes.
What options are you compiling with? (Are you using the
included Makefile?)

I always use:
-O2 -march=pentium4 -fprefetch-loop-arrays

Try also using -finline-functions
