Just wondering if anyone else sees this.

I'm using dosemu 0.66.7 on Linux 2.0.35, and I notice that DJGPP
programs sometimes crash.  It seems to happen only with nested programs
(make and gcc.exe, make and ln, emacs and gcc, etc).  It's also not easy
to reproduce reliably, though I can often make it happen by repeating
`make; make clean' many times in succession.

Interestingly, both the parent and the child generate register dumps,
and they are strange ones at that, showing several selectors as invalid
or null, and often DS != ES.  dosemu then gives a message like "DPMI
unhandled exception 0D- terminating client" (inexact).  I have also
turned on dosemu's DPMI debugging, but can't make head or tail of the
output.

I'm quite sure this is a bug in dosemu, but again, I can't reproduce it
enough to report it well.  I would try the development version, but I'm
in the midst of a libc upgrade and haven't got many of the necessary
libraries recompiled yet.
