Package: xulrunner-1.9
Version: 1.9.0.5-1
Severity: important
Gecko 1.9-based browsers frequently segfault on me upon calling
cairo_pattern_create_linear; this may be a cairo bug, in which case
please feel free to reassign, but so far I've only experienced
problems in Gecko-based browsers (Iceweasel and Epiphany).
Segfaults happen in a seemingly random manner, sometimes within
seconds of opening the first page in a new Iceweasel session,
sometimes about an hour into using it (or even more). I haven't
figured out a sure-fire method of reproducing it. Iceape 1.1.x (not
based on Gecko 1.9) seems to be unaffected.
I run KDE 3.5 from lenny, on an Athlon XP with an nVidia GeForce 6200,
and I get segfaults with every X.org driver ("nvidia" 173.14.09, "nv"
1:2.1.10-1 and "vesa" 1:1.3.0-4, current versions in lenny). So far
I've been unable to reproduce the problem on a computer with a
different video card (a Radeon 9200 Pro). Thus it may be
hardware-specific or due to some different configuration on the two
computers: please let me know what kind of information could be
useful, if any.
Meanwhile, I'm testing the official Mozilla build of Firefox 3.0.5 and
recompiling cairo, xulrunner and iceweasel with gcc from unstable
(4.3.2-2), to figure out whether the builds on debian archive are
miscompiled for some reason. I will report if I find out anything.
I include two samples of backtraces obtained with
$ iceweasel -g firefox-bin -d gdb
I've had segfaults on epiphany (-gecko) too, but haven't made a backtrace yet.
I have these debug packages installed: iceweasel-dbg, libcairo2-dbg,
libmozjs1d-dbg, xulrunner-1.9-dbg; please tell me in case I should
install any more.
Note the values for x0, y0, x1, y1, with abysmal exponents like -314:
I don't know enough about cairo to judge, are they even normal?
That's all for now, again, I will provide more information if I find
out anything, and if I've left out anything meaningful please feel
free to ask.
Best regards,
Pier Luigi Pau
