Don't know if this helps, but the problem also occurs if you replace

const int t;

with:

const opEquals(Bar ) {}

The function must be named opEquals. If it's named "foo", the ICE goes away.

The problem here is the const member needs an initializer. The error was
suppressed and ignored, though, causing the compiler to later fail.
