This test failure occurs in the ftfont test, which is an alternative
for the older SDL font API.
The cause does seem to be a change in FreeType 2.11.1, as the tests
pass with FreeType 2.11.0. Unfortunately, I can't see any relevant
changes easily. I suspect pygame might be dereferencing a NULL pointer
somewhere.
I did some testing and found that pygame 2.1.0 is the first recent
version not affected by the FreeType test issue.
I'll keep digging, but I'd strongly suggest migrating to the most
recent upstream version as soon as possible, as I had no problems
building it.
