Status: RESOLVED DUPLICATE of bug 233815

(Firefox :: General, defect)

Description

[oxai]

User-Agent:       
Build Identifier: http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/0.8/firefox-0.8-i686-pc-linux-gnu.tar.gz


The bug appears in the official firefox 0.8 release DL-ed from 

http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/0.8/firefox-0.8-i686-pc-linux-gnu.tar.gz

md5sum checks out.

The problem is: Browser imediately exits with the following message:
---
user@host~/firefox$ ./firefox
/home/core/firefox/run-mozilla.sh: line 72:  1848 Illegal instruction    
"$prog" ${1+"$@"}
---
System: debian woody. CPU: AMD K6-II 500MHz

The number (1848) in front of "Illegal instruction" changes every time the
program is run. i.e. consecutive runs give 7173 7185 7205 7217 7233.

I'm sorry, I probably should have done this earlyer. Hope this helps some..
I't seems my CPU doesn't know about the cmove instruction. What now?
Do I upgrade or do you recompile? I suppose I'll be shopping soon.. :-)

I'm getting the same error but in line 451.
Running on FC1 on a K6 500Mhz

bryner:
Is it possible that this is another side-effect of using --enable-optimize="-Os"
?
