Being the maintainer of the DJGPP port of Emacs, I build Emacs with
DJGPP every few days, and I never saw such a crash.  That includes the
current CVS which I just checked out.  This mail is being composed and
sent by an Emacs built from yesterday's CVS.

I'm using:

  gcc.exe (GCC) 3.3.3
  GNU ld version 2.14 20030612

(but none of the older versions ever crashed for me like that,
either).  My libc.a is a v2.03 with a few patches, but I doubt that
those patches could cause a GC crash.

Thanks.  I never tried USE_LISP_UNION_TYPE, and so I'm not surprised
it didn't work at first.

I guess you need to provide as much info as possible.  Please begin by
posting a full transcript of the build, starting from "config msdos".
Then I'd like to see your system configuration (what OS and version
etc.)
