Please specify the version of the compiler and the platform you're running it on.

dmd git HEAD as of a few days ago (fe0ab0df5cfe4aa9c1ec4ea140e5521767e28df5)

OS X, but also tested on linux

I get the error message, but no assert.

Can't reproduce it. Please reopen if it can be reproduced in HEAD.
