Well, I *had* a test case, but I did something to it which caused it to
not crash anymore in the same manner.  But in trying to re-reproduce the
crash, I've stumbled across something else fascinating (which may be the
crash in another form...)

I'm now running with the code in djgpp/alpha, per what Andrew Cottrell
suggested, on a Windows 2000 box.  When I run the attached script, my
computer performs the compile (as evidenced by the appearance of a .EXE
file in the directory) and then the computer goes unresponsive.  Many
seconds later, I get the following message:

./test.sh: xmalloc: ../variables.c:2292: cannot allocate 792674112 bytes (0
bytes allocated)

This only appeared when I added the FOO=`tmp_file_name` line - before
doing so, everything seemed to work properly.

Interestingly, under the "old" BASH and DJDEV, it blows up with a
SIGSEGV, just like I was used to seeing - again, after having compiled
the executable.

Here's the script - let me know what you think:

--------------------------------------

#!/bin/sh

# Return temp file
tmp_file_name ()
{
  echo "test_$$"
}


func1 ()
{
   FOO=`tmp_file_name`
   echo "In func1('$@')"
   gcc "${TMPFILE}.c" -o "${TMPFILE}"
   return 0
}

func2 ()
{
   echo "In func2"
   func1 "$@"
   return 0
}
