I took a closer look now:

 EFLAGS: 00010282
 eax: f6c0f080   ebx: 0000416d   ecx: 00010282 edx: f6c0f0f8
 esi: c040b078   edi: f6c0f0f8   ebp: f6dd1dbc esp: f6dd1db4
 ds: 007b   es: 007b   ss: 0068

 3c0:       b9 06 00 00 00          mov    $0x6,%ecx
 ... not important ...
 3cc:       89 d7                   mov    %edx,%edi
 3ce:       89 55 f4                mov    %edx,0xfffffff4(%ebp)
 3d1:       f3 a5                   repz movsl %ds:(%esi),%es:(%edi)
 3d3:       8d 50 78                lea    0x78(%eax),%edx
 3d6:       8b 4d f4                mov    0xfffffff4(%ebp),%ecx
 3d9:       89 51 18                mov    %edx,0x18(%ecx)  ## OOPS ##

So %ecx should be %edi-24 = f6c0f0e0, instead it's EFLAGS. Oops [indeed].
%ebp value is correct, I checked. So it seems a hardware, strong
radiation or an interrupt that didn't restore ecx.

Thanks for reporting.
