The problem is that I cannot reproduce this problem either. Some versions of
gcc 4.7 might be affected (the affected user uses 'Exherbo gcc-4.7.2-r2'),
others not. As far as I can tell, only Intel 32-bit code is affected.

Regarding -mrtd: I don't know if this command line parameter is used at all.
I've just asked the affected user for the complete command line. But a function
with 'cdecl,regparm(0)' should pass all parameters on the stack on 32-bit x86
machines, right? And even if some parameters are passed in registers, EDI is
normally not used, only EAX, EDX or ECX but never EDI.
