47.0+build3-0ubuntu0.14.04.1 crashes on remote X11 display

[randomtasks]

Much of the time, firefox 47.0 will crash when displayed remotely. Both local and remote PCs are Ubuntu 14.04 with all patches applied as of today.

To reproduce, log into pc1 console then "ssh -X pc2.domain.dom" then:

>firefox -P --no-remote
[7663] ###!!! ABORT: X_ShmPutImage: BadShmSeg (invalid shared segment parameter); 2 requests ago: file /build/firefox-sKY334/firefox-47.0+build3/toolkit/xre/nsX11ErrorHandler.cpp, line 157

Segmentation fault (core dumped)

This did not happen with 46.0.1+build1-0ubuntu0.14.04.3. It is stable, confirmed with downgrade on pc2.

Tested on 3 different systems with identical results.

1) >lsb_release -rd
Description: Ubuntu 14.04.4 LTS
Release: 14.04

2) >apt-cache policy firefox
firefox:
  Installed: 47.0+build3-0ubuntu0.14.04.1
  Candidate: 47.0+build3-0ubuntu0.14.04.1
  Version table:
 *** 47.0+build3-0ubuntu0.14.04.1 0

3) Firefox should launch and be relatively stable

4) Firefox crashes with one of the following errors:

Same problem found mentioned at <http://crashrecovery.org/firefox/ubuntu1404/>.

[asgard2 (kamp000x)]

I have a similar problem with ff 47, crashes mostly at google.com/maps and firefox is started as another user (xhost +SI:localuser:userX; sudo -u userX -H /usr/bin/firefox -P).

[Owen Dunn (osd1000)]

I can replicate this problem intermittently on amd64 machines but not at all on i386.

[Jiri Kaderavek (jiri.kaderavek)]

I can confirm this problem on Ubuntu 14.04 and 16.04 too (both amd64, ltsp environment). Resolved by downgrading to previous versions.

[Christoph Zysik (zeektk)]

happened to me on Debian after changing
"gfx.canvas.azure.backends" and "gfx.content.azure.backends" from cairo to skia

[Christoph Zysik (zeektk)]

I should mention, it works on Debian ( using skia ) for me - but it does not if I use remote X like
ssh -X/Y to somehost and having skia set on that host - it'll crash like mentioned in Bug report.

LTSP environment based on ubuntu 16.04 AMD64 with mate desktop. Firefox48 crashes 5 of 6 times when starting. Same if you start firefox via ssh -X.

Ubuntu 12.04 LTS 32 bit up-to-date
Firefox doesn't start

Running firefox from a terminal:

$ firefox
ExceptionHandler::GenerateDump cloned child 13499
ExceptionHandler::SendContinueSignalToChild sent continue signal to child
ExceptionHandler::WaitForContinueSignal waiting for continue signal...
Violations segment (dump the kernel image)

Firefox starts (without problems) from terminal if I run:

firefox --no-remote
