A memory leak isn't the same as a segfault (although I don't know how AIX responds to OOM).
Can you show that it's a memory leak ? Show RAM use increasing continuously and linearly with loop count.
How many loops does it take to crash ?
Could you obtain a backtrace ?
Thanks. I'll try to get all these informations, but it won't be before monday.
