--- Comment #1 from Rainer Schuetze <[email protected]> --- The problem rather seems to be fun: _D9test187723funFqZf: 0000000000000000: 55 push rbp 0000000000000001: 48 8B EC mov rbp,rsp 0000000000000004: 66 0F 6E C1 movd xmm0,ecx 0000000000000008: 5D pop rbp 0000000000000009: C3 ret the cfloat is passed in FPU registers to fun, but the function reads ECX. --
