src/druntime/src/core/cpuid.d line 544:

        immutable ubyte [] assocmap = [ 0, 1, 2, 0, 4, 0, 8, 0, 16, 0, 32, 48,
64, 96, 128, 0xFF ];


The real problem here is that a array initializer allocates, even if all the
data is static, and the compiler should probably be fixed, but in the mean time
I think we should go ahead and kill as many allocations as possible from
druntime, and this is one of them.

In my experimentation, I found just sticking "static" in front of this line
solved the immediate problem.
