Trying to compile the attached D source code crashes the compiler with error message:

Internal error: e2ir.c 1786

The example file is a bit large, but I can't possibly reduce it any further still triggering the error.

Here's a much reduced version:

--
interface SomeInterface
{
}

void main()
{
	SomeInterface[] arr = new SomeInterface[1];

	if (arr[0] < arr[0])
	{
	}
}
--

Additional notes, in case they're of any help to anybody:
	Changing SomeInterface to a class makes it compile, changing to a
struct says that opCmp() is required.
	If there is no comparison of two array elements (which can be the same)
it works - just accessing them doesn't cause the error.

Ok, thanks! I couldn't bother :)

So it's interfaces again. Somehow I get the feeling that interfaces are very unwelcome citizens in D.
