I think I found the cause of the problem
(although I still don't understand why this can
result in a segfault...).

Somwhere in the nasm manual, in a section about
building shared libraries, I found a remark
that ebx is used to store the address of the
global offset table.
In a code snippet, I saw that ebx was saved before
any further computations were done.
So I simply push ebx in the function prologue, and
pop it in the epilogue. Works just fine.

I don't understand, however, why the compiler
can assume that the function does not modify ebx.
Any ELF/shared library experts?

I will try to replace all inline assembler with
external nasm files in the next weeks.

Regards,

Georg
