Wed 04 Aug 2010 02:19:25 PM UTC, comment #5: Aah, the crash is caused by a function in a part of FreeType which is disabled by `make devel'. I could reproduce it now, and it should be fixed in the git repository. Thanks! |

Wed 04 Aug 2010 06:49:43 AM UTC, comment #1: I need a recipe to reproduce the crash with one of the FreeType demo programs. Calling ftview or ftbench from FreeType 2.4.1 under GNU/Linux works just fine for me, this is, the font is correctly rejected. Valgrind doesn't show any problems either.

FreeType 2.4.1 seems much more robust against bad font files but the attached CFF font still causes a crash. It doesn't look like a particularly serious crash at first glance. There's a wild pointer involved but it used as the basis of a read. |
