oh yes, i recompiled like this, in a configured source tree (look at
my original bug report for configuration details) i issued

% make CFLAGS='-Wall -Wno-switch -Winline -Wmissing-prototypes \
               -Wsign-compare -Wundef -Wstrict-prototypes \
               -Wpacked -Wshadow -Wmissing-declarations -g' beta

then i run src/xemacs under gdb, the typescript is below

i have a suspicion against builder_find_menu_accelerator, as i
frequently had problems with the meta key activating my
menubar... wait a minute...

ok, that's it! i commented the following line in my
~/.xemacs/custom.el

 ;'(menu-accelerator-enabled (quote menu-force) t)

and now xemacs-beta doesn't dumps core anymore on S-space!

note that xemacs-stable doesn't dump core, even when it sees the same
customization (see my own followup to my original bug report)

hth, ciao
