768726 - Firefox crashes on long exception stacks with Firebug and "Track Throw/Catch"

Status: RESOLVED DUPLICATE of bug 768446

(Core :: JavaScript Engine, defect)

Description

[Simon Lindholm]

User Agent: Mozilla/5.0 (X11; Linux i686; rv:16.0) Gecko/16.0 Firefox/16.0a1
Build ID: 20120623040202

Steps to reproduce:

Install Firebug 1.10b1, set the "Track Throw/Catch" option (which runs random stack traversal etc. on JSD onThrow) from the Script panel's menu, and disable Script, Net and Cookie panels. Keep the Console panel enabled, so that JSD is on.

Open Firebug on a page containing
<script>
function tower(f, n) (n ? tower : f) (f, n-1);
tower(function() { error.here; }, 1000)
</script>
and reload.


Actual results:

Firefox crashes.

With 39 instead of 1000, it never crashes; with 40 it consistently crashes.
Stacks look like bug 746076 but I can't reproduce that.

It might be a dupe of bug 768446 although their stack traces differ.

Comment 2

Seems so - I can't reproduce now.
