1342894 - Crash in libc-2.23.so@0x9889d

Status: RESOLVED INVALID

(Firefox :: General, defect)

Description

[z.vanya]

This bug was filed from the Socorro interface and is 
report bp-d5974174-a6fc-46d5-b913-b3b3e2170227.
=============================================================

I've been having this problem with ALT's build of firefox: firefox-esr-45.7.0-alt0.M70P.1 and 51.0.1-alt2 .

Now also with vanilla firefox 51.0.1 .

The --sync and --safe-mode don't make it go away.

If I open this URL under a fresh user, the crash is not reproduced. So, it must be some interactions in my profile...

But I'm reproducing it 100% after I restore the session and switch to the tab which is causing the problem.

I'm going to continue testing this with future versions of firefox...

Results: the crash is reproducible in firefox 53 (nightly).

The reason is probably not a bug in firefox, but a buggy libfreetype-infinality-2.4.11-alt6.M70P.2 , which was tracked down by me thanks to the backtrace. I've done tests with other newer versions of this package (and without it, with using standard libfreetype), and the crash doesn't reproduce itself in those cases -- https://bugzilla.altlinux.org/show_bug.cgi?id=33181 .
