--- Comment #17 from Erich Eckner <gcc at eckner dot net> ---
With that, I get a segfault in cpuid():

(gdb) run
Starting program: /tmp/a.out=20
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/libthread_db.so.1".

Program received signal SIGSEGV, Segmentation fault.
0x0000555555555191 in cpuid ()
(gdb) bt
#0  0x0000555555555191 in cpuid ()
#1  0x00005555555551ef in main ()
(gdb)=20

... same on x86_64 - maybe, there's a typo, somewhere?=
