[cairo] cairo 1.5.x and sparc

[Doug Klima]

Howdy all,

Some Gentoo guys doing some Firefox 3 work on SPARCs have discovered a
regression that's causing crashers in Firefox 3. They've managed to
identify a few more apps as well, (vlc and gucharmap) and found the
common thread being cairo.

Long story short, using git-bisect they came up with
http://gitweb.freedesktop.org/?p=cairo;a=commitdiff;h=901b0c97523a2da00ccf91cf4cee3bf55ce989b5
as the bad patch.

Using the latest git does not resolve the issue.

Most of their debugging was done in a /query window to me on IRC, but
our bug for it is http://bugs.gentoo.org/show_bug.cgi?id=203282

Since it's SPARC I'd venture a guess it's some alignment issue but I
haven't looked into it at all and won't be able to until after the New
Year, which is why I'm just kicking this over to the ML.
