bugzilla.gdcproject.org: No confirmation mail; cpuid.d:838:17: error: PIC register clobbered by 'ebx' in ' asm'

[kdevel]

I do not get a confirmation email from bugzilla after entering my 
e-mail address here: 
https://bugzilla.gdcproject.org/createaccount.cgi

I tried to build patched versions of GCC 4.8.5 and 4.9.4 but this 
happened:

.../gcc-4.8.5/libphobos/libdruntime/core/cpuid.d: In function 
'cpuidX86':
.../gcc-4.8.5/libphobos/libdruntime/core/cpuid.d:838:17: error: 
PIC register clobbered by 'ebx' in ' asm'
"cpuid" : "=a" a, "=c" c : "a" 0x8000_0008 : "ebx", "edx";
^

patch branch gdc-4.8 commit 
8b43f71621673c4d0f3f0665c397a1d80d5b434e

and

.../gcc-4.9.4/libphobos/libdruntime/core/cpuid.d: In function 
'cpuidX86':
.../gcc-4.9.4/libphobos/libdruntime/core/cpuid.d:838:17: error:
