This was found while fuzzing graphite2 revision d2f5be53a856e4252a7a26d7f2a40e03b7ea665e (>1.3.7)

To reproduce run:
./gr2fonttest test_case.ttf -auto -demand

Marking as sec-audit since I believe this was introduced after 1.3.7 (latest included version in Firefox)

Fixed? in 0c26852419dcacd76d21f066fba339908df636f0. This was a transitionary bug, introduced within the last couple of commits and now fixed. So could never be exploited.
