strace output from firefox
Description of problem:
If I go to Facebook or eBay, firefox dies immediately after clicking on the enter buttons with a buffer overflow.
I've have rebuilt against the latest xulrunner and gcc incase it was this, but I'm still getting the same error
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. go to facebook.com, enter details, click on go
2. do the same for eBay
I can go to the websites
Backtrace looks like xulrunner may really be at fault here...
If you have the backtrace (not the strace) can you please post it. That is, run firefox under gdb.
For some reason, ddd is complaining that I don't have the debug file installed, despite me enabling the repo, grabbing it and installing!

stack trace (run firefox, copy and paste results)
See bug 506952 . The glibc backtrace after the fortify fail is not specific enough to tell if its the same code or not. It would be good to have a full gdb backtrace.
You might want to rebuild xulrunner with the last attached patch there, or with --enable-system-hunspell to see if it would fix it for you.
Full explanation of debugging for firefox (which is unfortunately too complicated) follows:
First of all, could we get output of the command
rpm -qa *xulrun* *firefox* *mozilla* *flash* *plugin*
Please also install firefox-debuginfo (debuginfo-install is from
Then run firefox with a parameter -g. That will start firefox running inside of gdb debugger. Then use command run and do whatever you did to make firefox crash. When it happens, you should go back to the gdb and run
(gdb) thread apply all backtrace
This produces usually many screens of the text. Copy all of them into a text editor and attach the file to the bug as an uncompressed attachment.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.
Please check if this is fixed by xulrunner-1.9.1-2.fc12 in tomorrows rawhide
