Setting blocking because it might be the underlying cause of bug 618549.

Bisecting this and bug 618549 yields the revision: changeset: 58521:e35b70ffed69 user: Igor Bukanov <igor@mir2.org> date: Wed Nov 24 17:56:43 2010 +0100 summary: Bug 612150 - Eliminating JS_GetFunctionName. r=mrbkap

Backing this patch out fixes this and bug 618549.

The patch in some cases would return an empty string when previously it would return "anonymous" for a function without the name. I guess it lead to fallouts. So a quick fix would be to make sure that the old semantics is preserved.

This is what I am going to test. The patch makes jsd implementation to return "anonymous", not null or empty string, for anonymous functions.

I cannot reproduce the crash. What exactly "script panel" means?

(In reply to comment #7) > Script Panel: > > http://getfirebug.com/wiki/index.php/Script_Panel I will check this tomorrow.

This patch fixes this bug and bug 618549 for me.

Comment on attachment 498272 [details] [diff] [review] v1 I can also see that the patch indeed fixes the issue.

Comment on attachment 498272 [details] [diff] [review] v1 Just in the interest of keeping header dependencies in check, could jsfriendapi.h include just jspubtd.h, and have the cpp pull in whatever private headers it needs?

http://hg.mozilla.org/tracemonkey/rev/a42ff92a089e - pushed without including jsapi.h into jsfriendapi.h
