715080 - Infinite recursion cannot be stopped with "Unresponsive Script Warning" function

Status: RESOLVED DUPLICATE of bug 682793

(Core :: JavaScript Engine, defect)

Description

[Krzysiek Grzembski]

Attachment: ubreakable-recursion.html

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:9.0.1) Gecko/20100101 Firefox/9.0.1
Build ID: 20111220165912

Steps to reproduce:

Infinite recursion in javascript (see attached file - save for open). Firefox 9.0.1, Windows 7 Proffesional SP1, 64-bit.


Actual results:

"Unresponsive Script Warning" alert pops up but clicking "Stop script" doesn't stops script. Script is still running.


Expected results:

In google chrome i get "Uncaught RangeError: Maximum call stack size exceeded" and it would be the best option, but at least "Stop script" button should break scripts on page.

On Mac I get "Error: too much recursion" on the error console on both 8.0.1 and 9.0.1 -- I don't see the described behavior at all. Hard to imagine this behavior being platform dependent but will test Windows when I get a chance.

Reporter, do you have Firebug installed?

Comment 3

[Krzysiek Grzembski]

yes, i do.

On Nightly 12.0a1 without firebug i get error: too much recursion. So this is firebug fault?

Ok, did some more testing and you are right. This is caused by firebug. With Firebug disabled i get "too much recursion" in evry firefox version.

Yeah, there's a known issue with Firebug where it will try to do some sort of handling on the "too much recursion" exceptions, but that processing tries to use the stack, which is full, so throws that same exception again and round Firebug goes....  There are existing bugs on this.
