Does not show the problem on either -m32 or normal on my Fedora 22,
64-bit with any of:
Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz (inside a qemu though, where
it shows "Intel Core Processor (Haswell)")
Intel(R) Core(TM) i5-2450M CPU @ 2.50GHz
Unfortunately, I fried my AMD Bulldozer last week, so I cannot check
there.

jonas
