Status: RESOLVED FIXED

If you have a file, called fileAAA.html, which has an iframe, called
fileBBB.html, which... either (i or ii)
i) contains an iframe, sourcing fileAAA.html
or
ii) contains a subframe, sourcing any "parent" document

You get an endless/ redundant loop.

(This is of course bad web programming, but...)

Reproducible: Always

Steps to Reproduce:
1. create fileAAA.html with an iframe tag, calling
2. (create) fileBBB.html with an iframe tag, calling
3. (create) fileCCC.html with an iframe tag, calling
4. fileAAA.html

Actual Results:  
Nesting, nesting, nesting...

Expected Results:  
Mozilla should check, when loading an iframe, that the source, does not either
this' source, or any *parent source* of this.

*parent source*  would be any file, that contains and iframe, sourcing 'this'

It didn't crash on my Win2K box, but I'm guessing that a Win95/98 box might not
be so smart.  I'm not sure whether the nesting ever stopped or not, and if so,
by Mozilla or Windows.  All I know is that my Task Meter peaked, then dropped
off after a second or two.

Load this file... which loads fileBBB.html, which loads fileCCC.html, which
re-loads fileAAA.html, which loads..., ..., ..., ...

LInux 2003122707 loads each doc three times. You might try a newer build.
I did find a newer bug bug 228829 which looks to stop more creative uses for frames.
