Hi Brendan,

Thanks for the speedy reply.  Unfortunately, I don't have the assert in the
debugger anymore, so I can't check if script->object exists.  I'll check for
this if I hit this again.

But basically, this is what I'm doing:

1. call JS_CompileFileHandle() and get a JSScript*.
2. call JS_ExecuteScript()
3. call JS_DestroyScript()

So basically, compile, execute, destroy.  After executing the script, we
destroy it cuz we never use it again.  Is there anything wrong with this
sequence?  I'm not calling JS_NewScriptObject.  And oddly, we've never run
into this using rc5.

Ed
