I could not find any junk on my DJGPP.ENV. Renaming it makes Emacs to work.
However, even if I use the original DJGPP.ENV from the djdev201.zip the
problem shows up.

I feel your guess is in the right direction however: playing with
environment variables I can have emacs working or not, in addition to what I
reported in my earlier e-mail, these environment variables modify this odd
behaviour:

        if I unset my USER env var, or;
        if I unset my HOME env var, or;
        if I set GO32_DEBUG to y.
Emacs works w/o problems.

I then did the following tests: copied the _emacs.xmp to _emacs in both
c:/djgpp/gnu/emacs and c:/usr/csrabak to be sure that the problem was not
related to this file ('though crashes with the -q option, anyway). No
modification in the behaviour.

As you could surmise from my earlier e-mail, attempt to capture the
traceback w/redir did not cut! This time I made use of an old trick, using a
utility from ole PC Mag LPT2FILE and got the screen output (see below).

To symify this trace back does not show any other information as the emacs
binary seems to be built w/o symbols. (Also, I did not fetched the sources
for this new distribution).

This is the traceback I get:
