Subj : Breakpoint? To : netscape.public.mozilla.jseng From : "Sterling Bates" Date : Sat Nov 01 2003 02:17 pm Sometimes when destroying the context my CPU window will pop up at the ntdll.DbgBreakPoint. Following from there I get to ntdll.RtlLeaveCriticalSection (not sure why I was even in one...I compiled the engine as non-threadsafe), then MSVCR70.dll.free, and back to the JS engine (near a JS_HashTableRawRemove). Can anybody think of a reason why that would occur? Letting the application play out from this point seems fine, no exceptions at all. Thanks for any help :-) Sterling .
