I don't think it's 1439.  The crash actually only shows up when I use -g
or -gc when I'm compiling.  If I leave that off, it's fine.

It's when I try to use tango.math.random.Random that it starts crashing.
 I can use one method from that module, it's fine.  If I try to use more
than one, it blows up.  Note that it's quantity, not a specific symbol.

Plus, if I compile the module with just a dummy main method, it's fine.

It MIGHT be 424.  I'm getting the crash at EIP=004244FB.  I'm not
getting a fixups error message, if that's part of the symptoms, though.
My code isn't "template-heavy" (at least, not by my standards), but the
Random module does appear to be.

I'm toying with a little OMF dumper program at the moment.  I suppose
that's the easiest way to see if I'm hitting the fixup limit...

Incidentally, if Walter or yourself would like the object files causing
the crash, I can provide those (probably via private email).  I just
can't upload it generally since it's a private project.
