Subj : Re: AV in tear-down To : netscape.public.mozilla.jseng From : "Sterling Bates" Date : Sun Nov 23 2003 01:53 am It turned out to be some odd problem with allocating a certain variable on the heap from Delphi. Once I left that variable out, everything works. Probably a Delphi problem. I did notice, however, that one allocation (the profiler said four, but that may be four separate calls) by JS_XDRMemDataLeft is not freed by the engine. Whether that was a profiler's bug or SpiderMonkey, I can't tell. Sterling .
