The following message is a courtesy copy of an article
that has been posted to gnu.emacs.bug as well.


Thanks to Mike Dugan for suggesting the problem may be with unexec not
knowing about 64 bit a.out. However, specifying CANNOT_DUMP doesn't
help -- ./temacs still segfaults.  

This may be another hint

  # dbx ./temacs core
  Segmentation fault in Fmake_symbol at line 2543 in file "alloc.c" ($t1)
   2543     p->name = XSTRING (name);
  (dbx) where
  Fmake_symbol(name = 648518346342363900), line 2543 in "alloc.c"
  init_obarray(), line 3165 in "lread.c"
  main(argc = 0, argv = (nil), envp = (nil)), line 1092 in "emacs.c"
  (dbx) 

So, XSTRING is supposed to return a pointer to a lisp string. Might I
need to set something to define the size of pointers?   

Be gentle, it's been a long time since I did much C programming...
