Oh, what flags have you passed to DMD? I can only get a "Floating point 
exception" on OS X, which is, well, expected as it's the CPU that 
catches the integer-divide-by-zero error, not the language. The stack 
trace can be read by the debugger.

#0  0x00001e61 in D1y3fooFiiZi ()
#1  0x00001e4a in _Dmain ()
#2  0x00012357 in D2rt6dmain24mainUiPPaZi7runMainMFZv ()
#3  0x00011f01 in D2rt6dmain24mainUiPPaZi7tryExecMFMDFZvZv ()
#4  0x0001239f in D2rt6dmain24mainUiPPaZi6runAllMFZv ()
#5  0x00011f01 in D2rt6dmain24mainUiPPaZi7tryExecMFMDFZvZv ()
#6  0x00011e9b in main ()

Throwing an exception manually does produce a stack trace up to 'foo', 
just like Python (which traps divide-by-zero in the language).
