Huh, shouldn't this problem have manifested itself earlier then? 
Why only now? I don't remember this happening previously. At the 
very least I'm pretty sure I first encountered it last week. 
Unless something in DMD was patched? But then there'd be no way 
I'm the only one encountering this problem, and there don't 
appear to be any issues on github's tracker.
