This was found while fuzzing graphite2 latest revision (c9f2e111409ca160d3efc46daca83bb9fafab289)
It is triggering a large number of crashes and is blocking fuzzing.
To reproduce run:
valgrind -q ./gr2fonttest test_case.ttf -auto

Sorry. Can't reproduce :( I get an invalid font error. It is failing because the font has no glyphs in it. Did you send the right test_case?

Ha I can't repro with it either. I must have mixed something up. This one works though. Sorry about that.
