If qword is buggy then that needs to be fixed. Applying this patch will 
only hide the real bug in the compiler.

The compiler bug needs to be fixed first before this patch can be applied 
otherwise it is not reproducable anymore.

FYI i already analysed it a little a before my holiday, the bug only 
happends when optimization with -O2 is done.
