You need to compile (link) with /OPT:NOICF to work around an MSVC bug.  
See http://bugzilla.mozilla.org/show_bug.cgi?id=151066, mentioned in 
http://www.mozilla.org/js/spidermonkey/release-notes/JS_150_RC5.html.  
See also many postings in this group.  All of these are too hidden, 
though. We need a  big release note about this in every release-notes 
update.  I'll add that now.
