[Pkg-fonts-bugs] Bug#569548: fontforge: deterministic segfault

[Rogério Brito]

Package: fontforge
Version: 0.0.20090923-1+b1
Severity: important

Hi.

I found (in a painful manner) that fontforge dies when in a very
specific case:

* open the font file bchr8a.pfb (from texlive-fonts-recommended).
* select the character U+03BC.
* go to Element > Style > Add small capitals and hit enter.

I was trying to modify some fonts in such a manner that I could have
small caps for use with XeLaTeX. It died in this character for any fonts
that I tried, 100% reproducible.

Actually, it also segfaults with other symbols (which I can't quite
remember), but this one should already hint at the general problem.


Thanks, Rogério Brito.
