84953 - Crash: referenced function call

Status: VERIFIED DUPLICATE of bug 63930

(Core :: DOM: Core & HTML, defect)

Description

[Wojtek Podgorski]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9) Gecko/20010505
BuildID:    2001050515

Bad: This page CRASHES Mozilla. Works in IE5.

Reproducible: Always
Steps to Reproduce:
1. Create a layer named "Layer1"
2. call following in JavaScript:

2a) 
{
    alert( document.getElementById );
}

2b) 
{
alert( document.getElementById('Layer1'));
}

2c) 
{var gbId = document.getElementById;
alert( gbId );
alert( gbId('Layer1') );
}


Actual Results:  2a) shows alert dialog saying object is a function
2b) shows alert dialog saying [object]
2c) shows alert dialog saying object is a function
    THEN
    *CRASHES* with no informations

Expected Results:  step 2c) should display steps 2a + 2c combined.
so it should display an information that "gbId" is a function and then show
alert box saying return value is an [object]

var gbId = document.getElementById;

should return a reference to a function, and it seems to do so. 
typing document.getElementById('idhere') works, but when called thru gbId with
an argument, it crashes. same thing with all other functions. this certainly
works 100% well in Internet Explorer 5.

Hi Wojtek, could you test this bug with Mozilla0.9.1? A lot of bugs (specially
crashes) have been fixed since 0.9. It doesn't crash and works correctly for me
in build 2001060308 win2k.
Thanks alot for helping test Mozilla!
