I figured out how to reproduce this segfault: Set .emacs to the following: (custom-set-faces '(default ((t (:height 121 :family "something-invalid")))))Then start emacs and let the mouse hover over something that would display a tooltip. After a second or so you'll get the segfault.I can't reproduce this crash with the recipe you provided. Hovering the mouse over the buffer name in the mode-line, or over one of the links in the startup screen, displays a tooltip with no crash. I also did `xrdb -remove' to clear my X resources---again, no crash with the recipe.
My emacs had some Debian-provided patches, so I tried building fresh from CVS. I'm still having the same problem, and I can still reliably reproduce the segfault. Here's what I did:
$ cvs -d:pserver:anonymous@cvs.sv.gnu.org:/sources/emacs co emacs $ cd emacs $ ./configure $ make bootstrap $ make $ ./src/emacs -QThen I evaluated the above snippet and hovered my mouse over something that produces a tooltip. Presto, instant segfault. If I leave out the ':height 121' from the above snippet, no segfault.
Can anyone else reproduce this? Thanks, Richard
