I got a little more useful output using this:

$export PERLDB_OPTS="NonStop AutoTrace frame=2"
$ make test >& out.txt

Looking at out.txt, the output around the crash is below. It seems to 
come after exec($cmd). It looks like it can't spawn a new process.

btw, this is windows 7. new PC, 8 GM ram.

If you need the complete file out.txt, I can send it to you directly.

######### Forked, but do not know how to create a new TTY. #########
  Since two debuggers fight for the same TTY, input is severely entangled.

  I know how to switch the output to a different window in xterms, OS/2
  consoles, and Mac OS X Terminal.app only.  For a manual switch, put 
the name
  of the created TTY in $DB::fork_TTY, or define a function
  DB::get_fork_TTY() returning this.

  On UNIX-like systems one can get the name of a TTY for the given window
  by typing tty, and disconnect the shell from TTY by sleep 1000000.
