Crash when playing Lord of Ultima

[GoogleCodeExporter]

* I read everything above and have demonstrated this bug only occurs on 10.4Fx 
by testing against this official version of Firefox 4 (not applicable for 
startup failure) - specify:

* This is a startup crash or failure to start (Y/N): N

* What steps are necessary to reproduce the bug? These must be reasonably 
reliable.

1) Set javascript.options.tracejit.content TRUE

2) Go to www.lordofultima.com and play the game. It's free.

3) Once the game loads, click the "Trade" button on the left side of the screen 
(it's next to City Info, Recruitment, and Commands).

4) The Trade window opens, but any attempt to click on a tab at the top of the 
window causes a crash.

* Describe your processor, computer, operating system and any special things 
about your environment.

Power Mac G4 Quicksilver (2002) with OWC Mercury Extreme G4 1.4GHz (7450) 
processor. 1.5GB RAM. Mac OS X 10.5.8.

* If this is a startup crash or failure to start, have you tried restarting 
with a clean profile? Does this fix the problem?

N/A

* For crashes or startup failure (optional): paste in any information from 
Crash Reporter, or if you are able to run 10.4Fx in gdb, paste in the 
backtrace. You can often do it like this from within Terminal.app:

Program received signal EXC_BAD_ACCESS, Could not access memory.

Previous frame identical to this frame (gdb could not unwind past this frame)

* Include any useful additional information, steps you have tried, etc.:

This only seems to happen when javascript.options.tracejit.content is set to 
TRUE. If it's set to FALSE, the game (and the Trade window) works properly.

This also only appears to be an issue with TenFourFox 4 final release. Beta 13 
worked fine regardless of the javascript.options.tracejit.content setting.

Thanks for your help!

Thanks, Tony, I have a good idea what the problem is. I'm going to re-open 
issue 37 since this was probably caused by it.

Tony, grab 7450-4.0r; this should fix your problem.
