JavaScript interpreter crash issue (2.0.1-development) continues.

[asowani]

Further to my thread started earlier (#13655), I tried to understand working of the JavaScript interpreter code using gdb. A typical stack trace I got was given below. What I would like to understand is that whether the interpreter is going into recursive loops (#29 and #15):
#10 0x000000001262e824 in WebCore::reportException(JSC::ExecState_, JSC::JSValue, WebCore::CachedScript_) ()

Is this something valid or if this is the indicator of a trouble?

Thanks,

This is 100% normal. I'll have more to say in #13655.
