Is there a way to track down where memory is being allocated if I'm using

This is something I have *always* wanted. Unfortunately I don't think
it's possible to add such instrumentation without modifying and
recompiling Phobos. Even if you're using D2, which uses druntime,
there's no such thing.
This has been on my "to do" list forever. One of these days I'll
actually get to it :-)
Hm, actually..
If you *are* using D2, you might be able to replace the GC interface
with a "debug" interface that just forwards calls to the normal GC.
This is a capability druntime inherited from the Tango runtime - the
GC is separated from the rest of the standard library and can actually
be replaced at link-time. I don't know if D2 links all three parts of
druntime into a single library or not, though.
It does. Partially because the three-library approach seems to have
problems on Linux (there are link errors even though everything needed
is actually present). But the GC is still easily replaceable. In fact,
D2 provides an undocumented way to redirect GC calls, but I don't think
it will currently work for this form of interception--you'd end up with
an endless loop.
