Oh, BTW, could you attach Installation and the compiled simple init.el
to the bug report?
Also, do you apply any local patches to the XEmacs sources? Copies
(or pointers to them) might help.
Anything I could test to find out whether it is related to the
C compiler or 64-bit uncleanliness?
As I say, I don't know much about 64-bit or AMD vs. Intel issues; you
might ask somebody around you, including the Emacs people since they
have similar problems to ours with respect to our evil use of unions
and/or casting for Lisp objects.
For the C compiler, you could try building with Intel's compiler or a
BSD compiler, also older versions of GCC.
Get a build log and look for warnings other than the getopt.h
prototype warning (that's some sort of backwards compatibility thing
and doesn't actually affect the xemacs binary AFAIK) and "operation
has no effect" warning in emacs.c (that is a memory debugging tool).
Build with --with-xemacs-compiler=g++, --with-union-type, and
--with-debug for the same version of GCC and look for warnings. You
should filter with "grep -v 'deprecated conversion'" because of the
const char[] vs. char* issue, which I don't think is related, and even
if it were there are a million of those, of which exactly zero come
from src/bytecode.c.
