The machine has 32 gigabytes of memory[1], so I don't believe 
that for a second.

Any ideas?

In both cases, it is running a 32 bit dmd, just generating 64 bit 
code.

I don't see a 64 bit release though... might have to try to build 
it yourself from source using visual studio.

(and ugh dmd REALLY needs to get its memory consumption under 
control! maybe just enabling the GC would help sometimes.)

Yeah, no kidding!  Recently I also ran into trouble with dmd's memory
consumption competing with Firefox, another big, fat memory hog.  I had
to kill the Firefox process just so I have enough free RAM for dmd not
to bail out in the middle of compilation.

While the latest D motto seems to be fast, fast, and faster, fast does
you no good if you can't even finish compilation in the first place.  We
need to have an option to turn on the GC and/or otherwise push dmd
toward the memory end of the speed/memory tradeoff, instead of being
stuck up fast creek without a memory paddle.

It's a long time I don't understand why there's not a 64bit 
distribution...
(along with a debug build of rt/phobos, btw)
