No, I can't. If I do:

The crash does not happen anymore.

See above.

I'm beginning to suspect a compiler bug, since I'm using:
[mmutz@dirichlet mmutz]$ gcc -v
Reading specs from /usr/lib/gcc-lib/i586-mandrake-linux/2.96/specs
gcc version 2.96 20000731 (Linux-Mandrake 8.0 2.96-0.44mdk)

Achim, what compiler do you use? Don?
