134444 - Sits at 100% CPU grabbing RAM and stops responding

Status: RESOLVED WORKSFORME

(Tech Evangelism Graveyard :: English US, defect)

Description

[Alex Slater]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.9) Gecko/20020311
BuildID:    2002031104

When the URL (http://www.vertigogalleries.com/) is entered, the browser stops
responding to commands and nothing is rendered to the display at all. At the
same time the executable sits at 100% CPU and continuously allocates RAM.

The process has to be killed to carry on.

(The site displays fine in IE v5.00.3315.1000)


Reproducible: Always
Steps to Reproduce:
1. Enter http://www.vertigogalleries.com/
2. Hit enter

Actual Results:  The browser stops responding to commands and nothing is
rendered to the display at all. At the same time the executible sits at 100% CPU
and continuously allocates RAM.


Expected Results:  Displayed either the page, or an error message. Basically
anything other than hang and chew through RAM  :-)

Machine is running Win2k Pro SP2 with 640MB RAM on a P3-900Mhz.

Hmm. Probably site bug but we shouln't be freezing.

Confirming on linux trunk 2002033015 
os -> all

here's the bad code:
function preload(src)
{
    i=new Image;
    i.src=src;
}

preload_src=Array('nav_about_on.gif','nav_sales_on.gif','nav_vmp_on.gif','nav_galleries_on.gif','nav_gifts_on.gif','nav_picks_on.gif');
for(i=0;i<preload_src.length;i++) 
{
    preload('http://www.vertigogalleries.com/images/'+preload_src[i]); 
}

the code inside preload() modifies i every time causing the for loop to behave
incorrectly

WFM on Windows XP build 2002071108.
I peaked at the JS on http://www.vertigogalleries.com/.. doesn't seem they've
done anything about it, but perhaps this has been fixed in mozilla since this
bug was opened.

I'm not fully educated in the way we deal with evangelism bugs.. should this be
resolved WFM, or ?

WFM, reopen if you can reproduce this.
