I'm not calling it, spidermonkey calls it from JS_InitStandardClasses, and it crashes then. There's a define in the code (JS_HAS_XML_SUPPORT) which seems to be on. I'd just like to turn that OFF (don't need the XML support) to see if that fixes my crash, but I don't know where it's defined. It seems like that should be a compile time option, like JS_HAS_FILE_SUPPORT. As a matter of fact, I can't find the define anywhere except when it's used.

Note that I pre-create the global = object as a prototype, and use that to create all the "real" global = objects that are attached to scripts.

I attempted to = undefine it when I compile (i.e., -UJS_HAS_XML_SUPPORT) but that doesn't = seem to take it off.

Three questions:

1. Any = idea what could be causing this,
2. How do I remove this from the = compile (is it defined in a config file somewhere?)
3. Is there = documentation to all these defines so I can remove what isn't necessary? =

You = shouldn't be calling js_InitXMLClasses - that's an internal = function.

All you have to do to get XML is add JSOPTION_XML to = your call to JS_SetOptions. Eg in my case I have something like:
=
=A0=A0 JSContext cx =3D JS_NewContext(runttime, STACK_SIZE);
=A0=A0= = JS_SetOptions(cx,JS_GetOptions(cx)|JSOPTION_XML|JSOPTION_VAROBJFIX);
=
I didn't change compilation flags at all from previous versions of = the engine.

I'm not calling it, spidermonkey = calls it from JS_InitStandardClasses, and it crashes then.=A0 There's a = define in the code (JS_HAS_XML_SUPPORT) which seems to be on.=A0 I'd = just like to turn that OFF (don't need the XML support) to see if that = fixes my crash, but I don't know where it's defined.=A0 It seems like = that should be a compile time option, like = JS_HAS_FILE_SUPPORT.
