Hi all,

once again: I don't think this is a bug. In my opinion, it is only an
optimization. It seems to me that gcc 3.* likes to play strange games
with the stack, and we cannot assume ESP to be the same at the beginning
and at the end of the program...
If you want to do the check for debugging purpose, you will have to
compile with -O0 (some modifications to the cvs head are needed to
compile with -O0, and I'll commit them in the next days)...
Please, someone correct me if I am wrong.
Luca
