           Summary: xlib text test cases crash on mac (macports 1.4.0)
           Product: cairo
           Version: 1.4.3
          Platform: Other
        OS/Version: Mac OS X (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: xlib backend
        AssignedTo: cworth at cworth.org
        ReportedBy: Brian.Ewins at gmail.com

After bisection, the bad commit is 
96d8f58daf279238d3a1dfcd4ed3710014e2aeea

My build has 2 patches applied - Chris Wilson's patch to get autoconf 1.10
working, and I changed the extend-reflect test to use extend-repeat, a
different crasher that was interfering with bisection.

Part of the problem seems to be the last macports upgrade (now on 1.4.0) -
previously I was getting the text in xlib ok, now they all segfault.
I notice it's pulled in XFree86, xrender and render as dependencies of various
gnome bits and pango. 

I think this is really a macports bug, I'm filing it in case others see the
same thing, and to see if that commit rings any bells.
