Just a question and a few data points.

Firstly, was this a scratch build? This bug has been reported against a version
that doesn't appear in the updates for F13.

Nevertheless, from the backtrace we see that the crash occurred in
HideStrokePointsCircle(), which is in splinestroke.c.

I can confirm that Serafettin builds OK with FontForge 20090923 (i.e. the
version currently in F13). The boldening algorithm throws a lot of warnings,
but no crashes.

splinestroke.c was at version 1.46 at that time.

FontForge 20100501 included splinestroke.c version 1.56.

I can confirm oget's finding of a crash in this version. (Built direct from the
tarball, as I couldn't find this RPM.)

A new algorithm for stroking splines had been introduced between the two
releases (at splinestroke.c version 1.48), and the CVS log shows quite a few
oopses being fixed since that time.

splinestroke.c is now at version 1.62 in CVS.

Unless someone else get there first, I'll try the current CVS version of
FontForge tonight, but I wouldn't be surprised if this crash has already been
fixed in CVS.
