Description Jack Lovell 2017-06-15 10:11:38 EDT
Description of problem:
Firefox 52 32-bit crashes repeatably on a number of web pages (including about:support).

Version-Release number of selected component (if applicable):
52.1 and 52.2, i686

How reproducible:

Steps to Reproduce:
1. Install Firefox 52 from repository
2. Open about:support

Actual results:
Firefox closes. When started from a terminal, a segmentation fault is reported.

Expected results:
Firefox should be able to open it's own support page without issues.

Additional info:
Running firefox from the command line with the --sync option appears to prevent this crash (at least on the about:support page), indicating the problem lies somewhere with the graphics/drawing.

The following webpage causes the tab's content process on 52.2 to crash, even with the --sync option, though the browser survives:

GDB log with crash (no --sync option)

Steps taken to produce the log:
1. Run gdb /usr/lib/firefox/firefox
2. In gdb, type "run"
3. Open a new tab and nagivate to about:support. This causes the segmentation fault.
4. In gdb, type "backtrace"
5. Finally, type "kill" and then exit gdb
Comment 5 Martin Stransky 2017-07-10 04:59:44 EDT

#9  0x49d0cfe9 in ?? () from /usr/lib/libgdk-x11-2.0.so.0
#10 0x49d0d169 in ?? () from /usr/lib/libgdk-x11-2.0.so.0

The report is missing debug info from the /usr/lib/libgdk-x11-2.0.so.0 library. Please install missing debuginfos (run "debuginfo-install firefox" as root or install that by hand) and attach the backtrace again.

New GDB log with extra debuginfos

Same process to produce as previous log, but with gdk debuginfos installed.
Comment 7 Jack Lovell 2017-08-17 04:18:56 EDT
The problem still exists with Firefox 52.3.
