[Alan Liu]

User-Agent:       Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; InfoPath.1; .NET CLR 2.0.50727; .NET CLR 3.0.04324.17; InfoPath.2)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1) Gecko/20061003 Firefox/2.0

Setting breakpoints inside plugin code will not break execution of Firefox.  It will load and run through the plugin code, without breaking.

Reproducible: Always

Steps to Reproduce:
1. Open any plugin project in Xcode.  For example, the sample plugin with OSX at /Developer/Examples/WebKit/NetscapeMoviePlugin
2. Create a custom executable, point it to /Applications/Firefox.app/Contents/MacOS/firefox
3. Set a break point anywhere in the plugin.
4. Hit Build and Debug
5. Load sample page in Firefox for plugin
Actual Results:  
Execution keeps running.

Expected Results:  
Break into Xcode.

Does not happen when debugging with Camino, or Safari, using the same steps, and same plugin code.

The executabe code is in "firefox-bin",  "firefox" is a shell script
But then I get:
Program received signal:  "EXC_BAD_ACCESS".
mi_cmd_stack_list_frames: Not enough frames in stack.


2. Create a custom executable, point it to
/Applications/Firefox.app/Contents/MacOS/firefox-bin
