DMD with debug info?

[Jarrett Billingsley]

Would it be possible to get versions of DMD compiled with debug info?
This would be extremely helpful in, if nothing else, finding where in
the source hard-to-reproduce bugs occur.  I've got a bug that only
manifests itself in an almost-40,000 line program which I can't reduce
(seems to be related to the size of the code), and I don't think
Walter would appreciate _that_ as a testcase.
