DJGPP only dumps with USE_LISP_UNION_TYPE ??

[Jan D.]

Hello.

I was trying to get Emacs to compile on djgpp 2.03.  But it crashed 
every time in the dump phase, at the first GC.  I tried different gcc 
versions (2.95, 3.22, 3.42), different binutils versions (2.11, 2.15), 
with and without optimizations, with and without debugging but it 
always crashed at the same spot.  Since it crashed in GC, I tried to 
set the USE_LISP_UNION_TYPE (found a couple of errors and checked them 
in), and to my surprise, I got a working Emacs.

Does this sound familiar to anyone?  Shouldn't with and without 
USE_LISP_UNION_TYPE be the same at runtime?  I was wondering if this 
could happen at other systems besides djgpp, and if there is some 
subtle Lisp_Object handling bug somewhere.  I've attached some 
debugging output.  If anyone has any idea and want more debugging done, 
I can provide it.

Thanks,

        Jan D.
