Christoph, any idea what table/offsets you were fuzzing? It would really help tracking down the cause. I'm guessing somewhere in the glyf table but that probably needs to be verified.
For OSX cases, could you note when a testcase also crashes in Safari? That helps raise the priority when reporting it to Apple.
John, it is the glyf table. I am currently trying to reduce the testcase. Yes, Safari is affected too.

This will be fixed by the OTS sanitizer (bug 527276).
This is fixed on trunk and 1.9.2 by the sanitizer blocking the fuzzed font.

no longer crashes as it does in 188.8.131.52. (This was tested on OS X 10.6.5 but crash was verified first.)
