Problem reproduced by Dworkin, he's working on a fix, but a good fix
might take some time (i.e: don't expect it within the next hour :-)

As a workaround you can recompile your driver binary with the '-DDEBUG'
directive commented out in the Makefile in the dgd/src/ directory, as
the bug involves a mis-calculation of the required stack-space for the
code and the -DDEBUG directive means that DGD complains about this in
the way you saw rather than giving itself some margin.

Hope this helps,

Erwin.
