Like bug 978618, this will make it hard for me to know if I come across a new bug.

There's some big refactoring that needs to happen for error reporting before anyone does any specific fixes for stuff like this.

Yeah, the issue is that console does the toString async, not when you make the count() call, and does it from C++ code.  And in C++, for that matter.  So what were you expecting for the filename/lineno given that?

Really, this case should probably just silently do nothing or something.  There's a ClearException on the stack, but since JS is not running the JS engine decides to report the exception instead of setting a pending one or something, I guess.

In any case, we should first figure out what the right behavior is at all when ToString() throws an exception in count().  If only we had a spec here...

We no longer report an exception here.  We just report a count with "no label" as the label.  Probably fixed when we moved AutoJSAPI to always take ownership of error reporting.
