Problem when migrating from gecko 1.9.1.2 to 2.0

Hi,

 

I have a C++ embedding application, in which I'm using
nsIScriptContext:: EvaluateString() to execute JS commands.

Under Gecko 1.9.1.2 it works fine, but after migrating it to Gecko 2.0,
I get these assersions:

 

1. JS_ASSERT(!initialVarObj->getOps()->defineProperty); - in jsutil.cpp

When I get this assertion, the value of
initialVarObj->getOps()->defineProperty is js: proxy_DefineProperty

 

2. JS_ASSERT(entries); - in jsscope.cpp

After getting this assertion, my application crashes.

 

Does someone know why these assertions happen only in Gecko 2.0?

 

Thanks,

Annie
