Attached example works on Mac OS 32bit and crashes on Linux 64bit:
---------------------------
% ./teststruct
a: I'm Foo
core.exception.AssertError@teststruct.d(9): null this
---------------------------

When changing
    int x;
    int[] a;
    int[] b;
to, e.g.
    int x;
    int[] a;
or
    int[] a;
    int[] b;
problem disappears.

This may be related to issue 6047

I think the root cause of this might be issue 6983.

I thought this was a duplicate of bug 6758, but it isn't. Although 6758 is fixed, and even the wrong-code bug 6189, this still remains.

std.format.doFormat around line 4845 has enough version(X86_64) stuff that it looks like a Phobos bug. I find it a bit scary that it bypasses core.stdarg, and there are not enough comments in that code for me to trust it.
