Subject: Bug in coff2exe?

Hi,

   I compiled my program (jed386) with -g for debugging support.  In it, I
have a function that executes a command by calling one of the spawn
functions.  For everything in the world except coff2exe, this works fine.
For example, I can run `make' this way and everthing works up until the
`coff2exe' step in the makefile at which point it fails.  It works perfectly
if I remove coff2exe from the makefile.  In addition, simply running
coff2exe as a shell command from the editor crashes it.  Please note: this
only occurs when run via the spawn command.  If I run make from the command
line, everything works fine.  As I result, I am pretty sure the problem is
with coff2exe.

   My GO32 environment variables are: nodpmi core core 
It does not seem to matter too much whether or not I use `nodpmi'. The
corefile `core' is attached below.  I expected some form of meaningful stack
trace since I compiled with -g.
