Just out of curiosity I ran the tests during build under GDB (simply
inserting "gdb --args" right before the "{interpreter}" in the
overrite_dh_auto_test rule in debian/rules).
It seems like the segfault is in the freetype library, when loading a font,
rather than in pygame (though I guess the root cause could be pygame passing
garbage to freetype? - I have zero knowledge about the API).
Cc-ing Hugh in case he can provide some hints about what might be going on here.
This does not change the fact that it would be great to move to pygame2 :-)
loading pygame.tests.freetype_test
loading pygame.tests.ftfont_test
