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.

Chris made a suggestion on IRC that this was a possible fix: http://gitweb.freedesktop.org/?p=users/ickle/cairo.dirty;a=commit;h=90f8d34fb63ad41e1b38edd12fe9eb5bd9b6e678 It's not the same bug. I've nuked my dp setup, and reinstalled it clean (to do this you need to uninstall Apple X11 and install cairo, automake, libtool, and git-core). Testing with this quickly 1.4.0 is still working and passing the text tests, while HEAD crashes as above. I expect bisection will get me to the same place, the crash reports are still the same.
uh, somewhat ambiguous in that last comment - it is cairo 1.4.0 that works correctly.
Chris' latest patch: http://gitweb.freedesktop.org/?p=users/ickle/cairo;a=commitdiff;h=6f4ee099385a58e40d5b04ae4bf389508a874c9e resolves the bug for me.
I've pushed another version of the patch that Chris created, (by splitting the original up into about four pieces---two of which I've pushed). Here's the piece that should fix this bug: http://gitweb.freedesktop.org/?p=cairo;a=commitdiff;h=8c9f0f607b992c47b555b5eaff3c599a8c1eac57 Please test and let us know. Thanks, -Carl
