You sure you want proper bug reports for this? There still seems to be a
lot of issues. For example, none of these work for me (OSX 64-bt).
----
int4 a = 2; // backend/cod2.c 2630
----
int4 a = void;
int4 b = void;
a = b; // segfault
----
int4 a = void;
a = simd(XMM.PXOR, a, a); // segfault

I could go on and on really. Very little seems to work at my end.
Actually, looking at the auto-tester, I'm not alone. Just seems to be
OSX though.
