It's pretty frustrating.  People got the tests to pass for the xcb target
recently, then I started getting a couple crashes:


Might help if you provide more details on what problems you're having.  I
was hoping to update the docs on how to get as much stuff to pass as
possible, before these crashes.  

There's a good chance it's not something you're doing wrong, and if you
could help figure out what the problems are, that would be great.

This will at least reduce failures to stuff that generates different output
every time, or crashes.  There are additional cases where the output
doesn't match the references provided with the source, some of which might
be good to update.  Any idea which of the cairo targets is most relevant to
what you're doing?
