Re: [Devel] core in freetype2 code

[Joseph Olatt]

Hello,

I was able to resolve this problem by doing the following in FreeBSD:

# cd /usr/ports/x11-fonts/fontconfig
# make deinstall clean
# make reinstall clean

I had suspected that the core dump in freetype2 was probably because of
a corrupt font file or some such. So I started deinstalling and
reinstalling all the font related dependent packages and was able to
solve the problem.

It would be nice if freetype2 did not core dump because of corrupt font
files (I think I saw a comment in one of the freetype2 source files
conveyed the same message. I don't remember which file.)

I would have thought that a "portupgrade -a" would have taken care of
this. That is what I ran after my cvsup and unfortunately it did not.

At least, my problem is solved.

regards,
-j
