Trying to compile this program:

---
import std.stdio;
import core.simd;

void main()
{
    float4 a = 0;
    float4 b = 1;
    writefln ("a = %(%s %)", a.array);
    writefln ("b = %(%s %)", b.array);

    //float4 c = a - b; //this works
    //writefln ("a - b = %(%s %)", c.array); //this doesn't

    writefln ("a - b = %(%s %)", (a-b).array); //this doesn't
}
---

Results in "Internal error: e2ir.c 155" with "DMD64 D Compiler v2.060" on OS X
10.8.2

The errors seems to be with the expression "(a-b).array". If I use a variable
to store the expression value first, then all is well.
