Subj : What does SpiderMonkey own?

Serious frustrations here :)

I'm trying to help out a user of my bridge code and the garbage 
collector is taking me for a ride.  I think (because I don't know) that 
I need to know what _exactly_ SpiderMonkey owns/frees when I add a 
property/GC.

I'm getting "access violation at address 75636578 read of address 
75636578".  I'm sure that the fact that both addresses are the same is 
significant, and I feel silly for not knowing why off the top of my 
head, but I'm going to find out <g>.

More details: I'm using RTTI to recreate a live Delphi object within 
SpiderMonkey.  When I add the methods (which are simply JSObject 
properties whose class has the call property defined) the GC will throw 
the above AV.

If I do not add the methods, everything is completely kosher.  I'm 
simply using JS_DefineProperty and JS_SetPrivate on the defined object 
(would reserved slots work better?).  There's nothing unusual about this 
code, it quite resembles the property scanner which works perfectly.  Of 
course, I may be better off creating a generic JSNative to handle method 
calls.

Any help is appreciated,

Sterling
