The following code causes an internal compiler error with DMD 2.061:

import core.simd;

void main()
{
    int4 a; 
    __simd(XMM.PSHUFD, a, 0x0);
}

The compiler outputs:

Internal error: e2ir.c 3882

This code probably shouldn't even compile, since pshufd needs to arguments, not
one. But because the code results in an ICE, not an error message, I think this
is a bug in the compiler.

You are correct in that ICE's are always compiler bugs.
