DMD 2.055 Crashing on Windows 7 x64

[Mehrdad]

DMD 2.055 seems to be crashing on my computer (Windows 7 x64).

When I press Debug, I see it's doing so in CloseHandle, probably because 
I've turned on "Enable close exception" with Visual Studio's "Global 
Flags" tool. (It takes a reboot to take effect.)

So this means there's an incorrect handle being used somewhere... but 
interestingly, by the time it crashes, the output file is already 
produced. I don't have the time to make a debug build right now, but I 
thought I'd mention this so that it could be looked into at some point.
