Comment 4 zhoujingmiller 2009-08-23 21:12:11 UTC 
Since I passed arguments to rpmbuild to build bytecode interpreter and subpixel hinting in freetype (using fedora's src.rpm), it could be related to freetype. However, a cvs version and the 0622 version of FontForge still fails at the same font. The src.rpm is for freetype-2.3.9-5.fc11.i586 .
Comment 5 zhoujingmiller 2009-08-23 21:13:36 UTC 
Just forgot something --- I built with the cvs FontForge with bytecode interpreter support and the 0622 version without bci.
Comment 6 Kevin Fenzi 2009-08-24 23:07:56 UTC 
ok. I will see about reporting this upstream... 

Thanks for the bug report.
Comment 7 Kevin Fenzi 2009-09-03 16:11:07 UTC 
Just an update here. I posted to the upstream devel list and it seems this bug is hopefully fixed in cvs: 

"I think this one really depends on converting OpenType advanced
typographic features to Apple ones. At least that's where the crash
occurs.
This is now fixed in cvs."

So, as soon as there is another release I can whip up a package for you to test with, or if you are brave and willing to build from cvs to confirm it's fixed that would be great too.
Comment 8 zhoujingmiller 2009-09-03 19:54:05 UTC 
Thanks, Kevin, for the package, but I just tested the cvs version with "Version: 01:15 GMT 3-Sep-2009(20090903)" and "Library Version: 02:27 GMT 1-Sep-2009" and the TrueType font is generated successfully. So it is confirmed that the issue is fixed in cvs. (So this bug will be closed?)
Comment 9 Kevin Fenzi 2009-09-03 20:02:46 UTC 
Up to you. We can close it out now, or wait until the next release and I will close it when that release lands in Fedora. 

Which would you prefer?
Comment 10 zhoujingmiller 2009-09-03 22:34:45 UTC 
Since it is fixed already and people encountering similar problem will probably checking out later releases or cvs builds of fontforge, given that the information is still accessible to them, I would prefer to close it so that we get «less» bugs in total. So I will close it now.
