Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Adam Miskiewicz]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.1.1) Gecko/20090715 Firefox/3.5.1 FirePHP/0.3

I tried to implement a crc32 checksum function in Javascript.  In testing, no matter what I did, it kept reporting -1 as the returned value.  Logically, since it's never the browsers fault, I was convinced that it was a problem in the code.  However, when checking in any other browser - be it Safari, Internet Explorer, or Firefox for Windows, the value returns correctly. In Firefox 3.5 for Mac however, it consistently returns the wrong value (whether it's -1 or otherwise).

Reproducible: Always

Steps to Reproduce:
1. Go to http://sk3vy.com/crc-test.php in Firefox 3.5 on the mac
2. Open up a different browser on the same computer or a different one, and notice the different values.
Actual Results:  
The page returns -1 on Firefox 3.5 for Mac and "1249991249" (the correct value) on ever other browser.

Expected Results:  
It should have returned "1249991249".

This is not a Snow Leopard only issue.  Happens on Leopard and Snow Leopard.

I think this is a major problem when arithmetic on a browser doesn't work correctly, hence my severity ranking.

Did you already tried to set javascript.options.jit.content to false for a test ?

Reporter: The testcase is gone, DO you have a new URL or is this fixed ?

I put the testcase back - but it looks as though it has been fixed in the newest version.  Thanks.

Thanks for the fast response and I'm glad that it seems to be fixed !
I will change the resolution to wfm because fixed is only used for bugs with a source code patch
