Hello,
In both Emacs 25.1 and master (at 53f8f4b), calling find-font from an
Emacs built with X support and started with `emacs -nw' results in a
segfault.
In both cases I am testing on Fedora 25. The version of 25.1 I tested on
was Fedora's default version built with GTK, and master was built myself
with Lucid.
To reproduce:
- Run `emacs -Q -nw'
- Evaluate (find-font (font-spec :name "Anything-10"))
(It doesn't matter whether "Anything-10" is something made up or an
actual font on the system.)
The result of "thread apply all bt full" is attached. Please let me know
if I can provide any additional information.
John
