[gentoo-hardened] Error building x11-libs/qt on a hardened amd64 box

Hi list,

While trying to build x11-libs/qt port I got following error:

Following is an excerpt from "qatomic_x86_64.h" :

----8<----[ qatomic_x86_64.h ]---->8----
113 inline void *q_atomic_set_ptr(volatile void *ptr, void *newval)
114 {
115     asm volatile("xchgq %0,%1"
116                  : "=r" (newval), "+m" (*reinterpret_cast<volatile long *>(ptr))
117                  : "0" (newval)
118                  : "memory");
119     return newval;
120 }
----8<----[ qatomic_x86_64.h ]---->8----

Although I'm not sure, but is it due to running 3.4 series compiler, hmm...?

I've uploaded the complete build log there:

bytes)

If any other information is desired, please mention.

TIA
