Re: GCC bug? Compiled code gives seg. fault

[Martin Kahlert <martin dot kahlert at infineon dot com>]

I think, you run into a stack size problem.
Try 'ulimit -a' and look for the stack size limitation.

I assume, gcc -O2 works, because the program doesn't use
neither data nor dat and these variables are optimized away
completely.

Hope that helps,
Martin.
