I built today the latest snapshot of CVS HEAD and found a new
regression: the DJGPP port crashes at startup while debugging itself.
The crash traceback is below, in case someone has an idea.

Please try to give me a few more days to hunt this down, I'd like to
avoid the situation where the branch is cut while this bug is still
there.

TIA
