Comment 1 Gino McCarty 2014-02-10 12:26:14 UTC 
USE='-system-sqlite -system-cairo -system-icu -system-jpeg' emerge -1v firefox

fixed issue for me.. 
maybe a system lib is no longer compatible.. not sure which one..

Firefox backtrace in safe-mode with system cairo from git.

It's probably cairo. Firefox is crashing with cairo from git and latest from tree (1.12.16).
I'll try with USE="-system-cairo" and post results soon.
Comment 3 Dmitry Derevyanko 2014-02-10 19:22:48 UTC 
Can't reproduce with USE="-system-cairo". Is it a bug in cairo itself or just firefox is incompatible with mainstream cairo?
For reproduce just visit site "habrahabr.ru" with system-cairo enabled in firefox.
Comment 4 Reuben Martin 2014-02-11 03:36:03 UTC 
I'm having segfaults in libxul, but the only system USE flag enabled is system-jpeg.

I'm rebuilding now with system-jpeg disabled to see if that fixes it. But having system-cairo disabled does not seem to be enough for my case.
Comment 5 Gino McCarty 2014-02-11 03:41:37 UTC 
Hey all, Im still getting segfaults even with all -system-* 
but at least the browser itself doesn't crash as before...
..although something is crashing...

Here is the output

Comment 6 Reuben Martin 2014-02-11 04:41:55 UTC 
Disabling system-jpeg didn't fix it. Still crashing.

full bt with =x11-libs/cairo-1.12.16

I had the same issue with firefox-27. I had not updated cairo since last fall. So clearly the update from firefox 26 to 27 was the reason for those segfaults.

From a quick look at the code, cairo seems to be buggy here. The next instruct after the _cairo_clip_path_destroy call sets clip->path to NULL, but the latter is already NULL. The reason for this remains unclear to me and debugging proved difficult since the _clip_and_composite_boxes is called a number of times.

After re-emerging firefox-27 with USE=-system-cairo, I did not experience any crashes so far.

emerge --info firefox

Comment 8 Reuben Martin 2014-03-03 23:02:30 UTC 
I'm still having issues with this. But only on my AMD based desktop. My Intel based laptop does not have any issues. Perhaps this is an architectural specific optimization bug.

Probably not, I am on intel and I reported this issue, its more likely that your cairo or other system-* libraries are build differently between the two laptops..
Comment 10 Klaus Kusche 2014-03-18 09:13:36 UTC 
Similar situation here:
Firefox crashes on many webpages with system cairo (cairo-1.12.16-r1)
and is much more stable with -system-cairo.
Comment 11 Jory A. Pratt gentoo-dev 2017-08-26 17:57:04 UTC 
If you feel I have closed your bug and it is still a current issue, please reopen and update it completely. We will not work bugs that have no ebuild in tree any longer or can not be reproduced with a current system.

Thank You for your support and understanding
