>Synopsis: xterm segfaults when selecting missing font
>Category: system
>Environment:
System : OpenBSD 7.2
Details : OpenBSD 7.2-current (GENERIC.MP) #992: Thu Jan 26
10:04:35 MST 2023
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
When the primary selection buffer contains an invalid font name,
selecting that font from the xterm VT Fonts menu causes a segfault.
>How-To-Repeat:
0. Not required, but useful to ensure that the issue is not due to a
faulty configuration. Clear loaded resources:
xrdb -merge /dev/null
1. Load a bogus font name into the PRIMARY selection buffer. For
example,
echo "bogusfont" | /usr/local/bin/xsel -p
2. Start xterm with a missing font:
xterm -font bogus
(Alternatively, skip step 0 and have a typo in the font name for the
corresponding resource.)
3. Holding Ctrl, right click on the terminal and pick "Selection" from
the "VT Fonts" menu.
