24.0.50; crash because of missing font for menus |
|

Hello!
Trying to debug a failure in font handling by the X server – XQuartz
2.5.1 (xorg-server 1.8.0.902) – I removed some elements from Font
Path. When I now open a menu either from menu-bar or by making it pop
up, GNU Emacs reports:
Warning: Cannot convert string "-*-frutiger linotype-bold-r-normal-
*-10-*-*-*-*-*-iso10646-1" to type FontStruct
It comes from the X resource
Emacs*menu*font: -*-frutiger linotype-bold-r-normal-*-10-*-*-*-*-*-
iso10646-1
When the menus just open no crash happens. It also does not happen
when I select an item from a menu I open from the menu-bar, as in this
case, when I invoked the function to report a bug from the Help menu.
The crash happens when I select a menu entry from a pop-up menu or
close the pop-up menu after I have entered the next menu level. So it
works to change text font size, but buffer selection or selection of
another font or fontset from the next menu level lead to the crash,
and just closing that menu unused as well.
GNU Emacs 23.1.93 complains the same way about the font, but it never
crashes.
BTW, the X resource setting does not seem to work well: some other
font is used, one, which is *always* available. I also remember that
some update (bzr pull -v) mentioned a message that due to some changes
in text handling of Xaw based menus (to display UTF-8 encoded text
correctly) some X resources were changed. Where are these names
recorded or documented?

It isn't pollution that's harming the environment. It's the impurities
in our air and water that are doing it.

I can't reproduce this. Does it work if you remove that X resource, or
if you put in a font that exists?
The resource is deleted (the font is available), only
Emacs.menu*borderColor: DeepSkyBlue
Emacs.menu*borderWidth: 3
Emacs.menu*shadowThickness: 3
Emacs.menu.attributeBackground: lavender
Emacs.menu.attributeForeground: DarkRed
Emacs.pane.menubar.margin: 2
Emacs.pane.menubar.shadowThickness: 3
exist. GNU Emacs crashes every time, independent of GCC version or X11
distribution or whether launched with -Q or not or as some other user.
I found a bug, please test it. FWIW, I only get it with your resources and
with an optimized Emacs build, and even then it only happens very seldom. It
is a race condition of sorts.
