Sorry, but that works fine here (commit 9a3ad1d from August 31). Running
"CAIRO_TEST_TARGET=image /usr/bin/time ./cairo-test-suite
pthread-show-text" finishes in 50 milliseconds.

I always tried to stay away from the font stuff, so I cannot comment on
that, but I *think* that is allowed to use the same font face from
multiple threads, so just removing all caches would not solve all thread
issues.

Yup, I never saw the test suite passing either.

Well, there are some crash reports in GitLab. I vaguely remember one
with a patch where the patch is just "let's make this array slightly
larger, because that seems to make the crash go away". I do not really
like that since it feels like it could just hide the real bug. How would
you deal with that?

Cheers,
Uli
