I'm working on it.  I can reproduce the problem, but not with emacs -Q
(only with loaded .emacs).

What I do is 
- start emacs 
- C-x 5 f /PATH/TO/EMACS/src/xmenu.c

Program received signal SIGSEGV, Segmentation fault.
0x08086f5c in digest_single_submenu (start=3803, end=4928,
    at xmenu.c:1850
1850                save_wv->contents = wv;
(gdb) p save_wv 
$22 = (widget_value *) 0x0

As you can see, the problem is at a little bit altered location,
compared to my last report.  I can reproduce _this_ problem absolutely
reliable, but only with .emacs loaded.

I'm not sure what to look for in .emacs that might cause the
problem -- but in any case I would think that lisp code shouldn't
cause a SEGV in any case.

btw. this is latest CVS Emacs, with lucid toolkit.
