Description Craig Ruff 2003-07-08 15:45:19 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030624

Description of problem:
I happened to access a web site that caused the xfs server to die with a SEGV
(according to strace).  It turns out that the web site
(http://www.upgradeware.com/tw/index.htm) used a Taiwan Big5 font, which I did
not have installed.  Installing them (taipeifonts-1.2-23) stopped xfs from dying.

Version-Release number of selected component (if applicable):
XFree86-xfs-4.3.0-2

How reproducible:
Always

Steps to Reproduce:
1. Start X without the Big5 fonts installed.
2. Use mozilla to access http://www.upgradeware.com/tw/index.htm, for example.
3. xfs dies, mozilla hangs.  Restarts of X fail because xfs is not running.

Please report this in the XFree86 upstream bugzilla located at
http://bugs.xfree86.org and update this report with a URL linking to the
upstream report for tracking purposes.

Thanks.

Thanks, setting bug state to UPSTREAM to track in the upstream bugzilla.

Comment 4 Mike A. Harris 2003-07-17 10:49:03 UTC

The upstream bug report has been closed WORKSFORME.  Without ability to reproduce
freely and without further debug info such as a backtrace, I'm unable to
investigate this any deeper.  If you can provide any more debugging information,
please continue to add it to the upstream bug report as I'm CC'd there.

Comment 5 Craig Ruff 2003-07-17 13:12:52 UTC

Of course, once I decided things seemed to be working, it failed again.
This time it was with the Big5 fonts installed.  It may be to some
TrueType fonts I have installed, but I have not yet been able to
narrow down which one.  This is the stack trace from the failure point:
