Hi everybody, I'm having some problem with the GC. My application is
spidermonkey based and it is ending with an abort after I call JS_GC. I
find out that this abort is generaed at:

UNMARKED_GC_THING_FLAGS(void *thing, void *arg)
{
    uint8 flags, *flagp;

    if (!thing)
        return NULL;

    flagp = js_GetGCThingFlags(thing);
    flags = *flagp;
    JS_ASSERT(flags != GCF_FINAL);          <<<<<<<<<<<<<<
#ifdef GC_MARK_DEBUG
    if (js_LiveThingToFind == thing)
        gc_dump_thing(thing, flags, arg, stderr);
#endif

    if (flags & GCF_MARK)
        return NULL;

    return flagp;
}

Any suggestions?

Another few question:

- The root object of a ctx should be rooted?
- If the ctx root-object isn't rooted, after calling JS_GC this will
collected and disapear?
- After a sequence of operations on a ctx root-object ( properties
definition, scripts executions, etc. ) the best way to erase any
reminder information, before starting a new iterarion, will be:
             a) calling JS_GC? What happend if the root object is or
not rooted?
             b) use rooted ctx root-object and call JS_ClearScope?

Best regards.

Carlos
