Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; it; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; it; rv:1.8.0.7) Gecko/20060909 Firefox/1.5.0.7

I experienced this problem only on a PC equipped with Athlon Thunderbird CPU.
Running this PC with MS Windows XP everithing works fine (Firefox too), but if I try to execute firefox after a clean linux installation, the program crash.
I tried with the following distros: Knoppix 5.01 (live CD), Ububtu 6.06 LTS (both live and install with latest patches/updates), Fedora Core 3 and Fedora Core 4.
I got this problem even if I try to create a virtual machine with Linux under VmWare.
The only PC I experienced this problem is equipped with the following CPU (I got the output from cpu-z 1.37)


  Name .........: AMD Athlon
  Code Name ....: Thunderbird
  Brand ID .....:
  Package ......: Socket A (462)
  Technology ...: 0.18um
  Voltage ......: 3.038 v
  Specification : AMD Athlon(tm) Processor
  Family .......: 6
  Model ........: 4
  Stepping .....: 4
  Ext. Family ..: 7
  Ext. Model ...: 4
  Revision .....: A9
  Instructions .: MMX(+), 3DNow!(+)

Last try I made, is to debug this crash under a VmWare virtual machine running Ubuntu 6.06LTS with latest updates. I follow the instructions found there https://wiki.ubuntu.com/DebuggingFirefox, and this is the output I got from debugger:

I never had any problem like this using different PCs and CPUs, and I cannnot try to reproduce the problem using another PC with AMD Athlon Thunderbird CPU.


Reproducible: Always

Steps to Reproduce:
1.install a clean linux ubuntu 6.06lts on a pc equipped with athlon thunderbird cpu
2.try to execute firefox from bash console

Actual Results:  
you got a segmentation fault error and firefox doesn't start


Expected Results:  
firefox starting

As I said before, I suppose the crash is because of my CPU (maybe some kind of optimization my CPU doesn't like). I know this kind of CPU is not easy to retrieve to perform needed tests, but I'll be very happy to give my support for every kind of needed tests.

Next time it happens, can you try getting a stacktrace using the steps outlined here: http://kb.mozillazine.org/Getting_a_stacktrace_with_gdb ?
