           Summary: non-XFT builds of Mozilla crash X server when viewing
                    pages with unrecognized unicode characters
           Product: xorg
           Version: 6.7.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: critical
          Priority: P5
         Component: Fonts/other
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: fedora at ancientcoins.biz


Non-XFT enabled builds (-> official mozilla.org builds; tested 1.7RC1, 1.7RC2,
1.8alpha) crash the X server on Fedora 2 (xorg-x11) when viewing pages with
unrecognized unicode characters.

See the links for examples:

A png of the characters causing the X crash:

This page with just 2 characters crashes X on Fedora 2 with 1.7RC1, 1.7RC2 and
1.8alpha (non-xft):
http://www.captn.net/mozilla-crash.html
(self built XFT-enabled doesn't crash)

This is especially annoying when such characters appear in google SERP's!

Can't come up with any useful error-messages yet. Reasons:

* X crashes only with:
Fatal server error:
Caught signal 11.  Server aborting

* mozilla -g | tee mozdbg.txt
stops writing to the file as soon as X crashes

If you have any other ideas on getting error messages, I'd be more than happy to
post them.

Thanks a lot!

Reproducible: Always
Steps to Reproduce:
1. Install any recent non-xft mozilla-build on Fedora 2
2. View the page mentioned above
3. X server crashes

Actual Results:  
X server crashed - Fedora-graphical login comes up again. Sometimes hard hang of
the system
