I can reproduce on s390x too -> Program terminated with signal 11, Segmentation fault.

Comment 2 Tomas Pelka 2016-03-09 17:31:37 UTC
s390x seem to be fine with firefox-45.0-3.el7_2.s390x, arm still segfaulting

Comment 3 Jon Masters 2016-04-12 17:02:51 UTC
Can you provide some information about the test platform? Which machine?

Comment 5 Laszlo Ersek 2016-09-21 21:51:04 UTC
I'm not seeing this (immediate) crash with firefox-45.3.0-1.el7_2.aarch64.

I do encounter the (delayed) crash reported in bug 1358441. For that bug, I think I actually have an analysis (no hard proof or patch yet), so I'll continue there. I originally thought this BZ would be a duplicate, but the stack dump in comment 0 here looks very different, so these two are likely not duplicates.

(OTOH, as I said, I can't see *this* kind of crash at all, so maybe we can close this as WORKSFORME, if it stops reproducing for everyone else too.)

Hi Tomas,

if the question is addressed to me, then I don't understand it. As I wrote in comment 5, I couldn't reproduce this specific kind of crash at all, even with "firefox-45.3.0-1.el7_2".

Regarding "firefox-45.4.0-1.el7_2" (which you linked in comment 6): the fix that I prepared for the other bug 1358441 works well on top of firefox-45.4.0-1, so firefox-45.4.0-1 is certainly a good baseline -- with my build I'm not seeing any crashes at all.


If your question is addressed to the other subscribers of this bug, so that we learn whether firefox-45.4.0-1 reproduces this specific bug for them or not, then sorry for the noise.

Comment 8 Tomas Pelka 2016-09-23 06:39:51 UTC
Yeah I had commented before I read your message till the end, so simply ignore it. 

Sorry for confusion.
