issue with gcc 4.x optimizations

[Martin Quinson]

For information, I've solved my issue. A part of my code was doing an
overflow in an array stored on the stack. It looks like %ebx is stored right
after user data, but only reused with dynamic linking and some optimizations
enabled (or so).

That is why it worked without optimization: I was overwritting a useless
value in that case.

Hoo-ray!

I am deeply sorry for this list polution.
Martin Quinson.

I muck with indices and structs all day.
And when it works, I shout hoo-ray.
