Bug#656359: [Pkg-fonts-bugs] Bug#656359: [Pkg-fonts-devel] Bug#656359: Segfault when pressing modifier/arrow keys if more than 4 points are selected

2012-01-19 Thread john knightley
Dear Khaled

the segmentation fault is somewhat erratic for example moving around the
letter g does not crash but moving say a character at uf8000 does - in some
cases starting a new font, making it full unicode  going to a higher point
and simply pressing element is sufficient to crash. Even if somewhat
difficult to describe there is indeed a serious problem here. I have one
machine running ubuntu 9.10 which I have been doing all my fontforge work
on because when I update to ubuntu 10.4 I noticed this bug, which has
remained though I have updated to 10.10 .

Over the past week I have been preparing to do a fontforge training session
in Feb and I myself thought that install rather than updating to Maverick
solved the problem because I only tested 'g' .

Regards
John

  Hi fontforge folks--
 
  over on Debian, we've just gotten http://bugs.debian.org/656359, which
  appears to contain a reproducible segfault.
 
  Some folks have suggested that it may be due to more recent versions of
  dependent libraries, but i haven't been able to track it down in more
  detail, i'm afraid.
 
  From Theppitak's original report, a recipe to produce the crash:
 
  Steps to reproduce:
  - Start fontforge and create a new font.
  - Randomly choose a first glyph to edit.
  - Draw splines with at least 5 points.
  - Select up to 4 points and press a modifier or arrow key. It won't
 crash.
  - Select at least 5 points and press a modifier or arrow key. It will
always crash.
 
  Any suggestions?

 I can't reproduce this with fontforge built from git master running
 under Ubuntu 10.04.

 Regards,
  Khaled

I use FontForge extensively I never encountered this, and generally it
is less crashy than it used to be. May be it is 64bit specific bug?

 Khaled
