1174579 - firefox illegal instruction crash during startup on centos 6.6

Status: RESOLVED WORKSFORME

(Firefox :: Untriaged, defect)

Description

[mdflickner]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.65 Safari/537.36

Steps to reproduce:

firefox --safe-mode

I see firefox crashing with illegal instruction on certain centos 6.6 virtual machines. This relates to this thread - https://www.centos.org/forums/viewtopic.php?f=14&t=49418

I created a new centos instances on softlayer where firefox works. I used this image to create a new instance where firefox --safe-mode fails with an illegal instruction. 

All images have the latest updates with firefox 38.1.1. I tried yum remove firefox followed by a yum install firefox. I also tried regressing firefox back to version 31. On a failing machine I tried chrome using install_chrome.sh from http://chrome.richardlloyd.org.uk/. It also gave me an illegal instruction. 

How can I track this problem ? 

Is it possible this is caused by virtualization ? I noticed the instances that fail/work have different processor versions.

Expected results:

If you're installing firefox with yum, you're not using a mozilla.org build of firefox. Please try with a mozilla.org build of firefox: https://www.mozilla.org/en-US/firefox/all/
If those builds work, file a bug on the centos bug tracker.

That's a crash in virtual machine - I'd investigate it by this way. It's also x86_64 so the instruction set may not differ between real and virt HW.

I successfully ran the mozilla version of firefox on a centos instance that failed.  Will followup with a centos bug submission.
