[Bug awt/28804] New: segfault in libfreetype (debian) with e.g. Java2Demo

[twisti at complang dot tuwien dot ac dot at]

When running Java2Demo from SUN, I get the following segfault.  It seems that
this happens only on Debian systems, as other people (Robert Schuster IIRC)
haven't seen this crash with a different application (which I also can't
remember anymore, sorry).

Program received signal SIGSEGV, Segmentation fault.

The CACAO output of that segfault is:
