This problem was just fixed by matthieu in X:
CVSROOT: /cvs
Module name: xenocara
Changes by: matthieu@cvs.openbsd.org 2019/10/28 13:38:47
Modified files:
dist/fontconfig/src: fccompat.c fccache.c
Log message:
Stop calling chmod() in cache update code.
These calls are useless to toxic and come in the way of adding pledge
to applications (would require 'fattr' which is quite wide).
Discussed with deraadt, millert and jcs.
Submitted upstreams too.
The problem was specifically discover in firefox with pledge and
fattr, just as you experienced, but too close to 6.6 to fix for the
newfangled pledge/unveil stuff that is coming.
Surely you are probably running older code. And your pkg changes
caused a font input to change, and therefore the library wanted to
do a silly chmod.
