Aidan is right, we should use "monospace" and let fontconfig do the
work.

I think we should warn (although not in the inimitable jwz style! you
know, the xmodmap kvetching) if we detect something in the fontconfig
we don't grok, of course, but I don't think we should try to work
around it.

Very strange.  I fixed a bogosity in my code that prevented the
fontconfig substitutions from getting properly applied, which may not
be in your xemacs yet (the src/ChangeLog is

), but if you request a specific font that you do have by name, I
don't yet see why you would crash, even without that patch.

Can you give me a C backtrace?  All the Lisp backtrace tells me is
that some fontconfig code is being called, but I don't see anything
wrong with the code just looking at it.

You should reenable the Xft debugging output, set debug_xft=1 in gdb.
If you do that, make sure you add the patch above which adds printout
of the truename of the font we're initializing.  (The variable is
defined in xft-fonts.c if you want to do it permanently, but once
you've got XEmacs to stop crashing in font operations, that output
becomes completely uninteresting, until you start fiddling with Mule
fonts.)
