emacs 22 seg faults this morning

[jpff]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

I tried looking at p but gdb did not admit it existed

Setting a breakpoint was not much help as it was after many calls
