Indirect recursion only working with a breakpoint inserted

Maybe someone can find what I'm doing incorrectly...

I'm doing a fairly literal port of json_parse.js from Douglas Crockford. It's an indirect recursive descent parser that uses a global to track where it's at in the JSON string that it's parsing. Essentially, value() calls object(). object() may then call value(), and so on. Works great... as long as my value.vi has a breakpoint inserted at the beginning. Take the breakpoint out, and the vi doesn't... really seem to execute. Or it does, but unpredictably.

Does anyone have any insight into what might be going on here? The code was crashing with an access violation. I spoke with an AE, and he said my top level VI was corrupted. Replacing the LV native globals with an LV2 global fixed the crash, but hasn't fixed the execution issue.

Code's attached, if anyone has any insight. Parse.vi is the top level. (Sorry, haven't had a chance to implement array() yet...)

Thanks,

Joe Z.
