108498 - Infinite loop in javascript console (may be unrelated to console)

Status: RESOLVED DUPLICATE of bug 85831

(Core Graveyard :: Error Console, defect)

Description

[Kendes]

While debugging a web page (using for reference, window.open() then in child
doing things like opener.location = ".../etc" or opener.location.ref= "../etc"
style, then a this.close()) - I got an exception in the console. Didn't manage
to get the full text of it but was something like:

chrome:// ..... /addItem ()..
This appeared to be in an infinite loop - consuming 98% of CPU. The console
could still be closed and the rest of the browser worked normally, other than
the 98% CPU. Exiting the app did not kill the process in task mgr  -- had to
kill it manually.

JS console.  I've seen this on Linux too but can't come up with reliable steps
to reproduce...  The issue is that addItem() gets undefined somehow or at least
something thinks it is.  The resulting exceptions swamp the JS console.

Might not this be a dupe of bug 85831?

So it is.  Thanks, David!
