Check the assembler output ("gcc -S ...").
Personally, I'd be more inclined to suspect register corruption. Are
you calling a library function which use a different ABI? E.g. if your
code is compiled for an ABI where certain registers are preserved but
calling a function using an ABI which doesn't preserver those
registers, then you'll have problems.
