I'm a bit confused by this.  In the first quote above you said that this
was a coding error and ought to be fixed in qt, but now you seem to be
saying that it's a compiler bug and should be fixed in gcc.  If it's the
latter, can we get that patch applied to the oe-core version of gcc?

Either way, I agree, working around this by just frobbing the
architecture options seems like a bad idea.
