This one compiles on 2.059 Win32, but crashes with "Access violation" at runtime.

Checked on git HEAD: the ICE no longer happens, but now a runtime exception is thrown: object.Exception@std/stdio.d(1442): Enforcement failed Looks like some kind of bad interaction with AA's and struct dtors.

The runtime exception is the dup of bug 6178. *** This issue has been marked as a duplicate of issue 6178 ***
