I tried this in my Firefox, but it didn't crash. The text, however, became 
almost black, overwriting itself many times. 
 
But I have a similar problem: Long lines of text in various KDE applications 
crash Xorg. It's _quite_ reproducible. The "nv" driver doesn't crash in the 
same situations. 
 
More information about my problem here: 
http://forums.gentoo.org/viewtopic.php?t=282107 

I played some more with the long link in Firefox, and suddenly it locked up  
the CPU. It went to 100%, completely blocking the machine. It didn't crash for  
several minutes, and then I ctrl-alt-backspace'ed it. 

starting with the 6.8.99.14 snapshot, on linux systems, the X server can print
its own backtrace when it crashes.  please confirm that these bugs are still
valid with 6.8.99.14 or later, and if they are please attach a the server log
from the crash.

I'm not sure I can do that backtrace, but I'll certainly give it a try when I 
get around to updating. 
 
I've just found another way of crashing X with Firefox. I loaded this 
extension: "View Rendered Source (Firefox Extension) Version 1.0.01". When I 
try to use it, X resets instantly. 
 

i to have experencied this problem, and have found it very very reproducible, i
was writing a php script that made very long urls (over 2KB) and when firefox
reached it crashes almost instantly (if not just try again, quit firefox again
and try it, i get about a 75% crash rate)

i was also able to get a backtrace, but i do not have debuging info in my X
server so it dosen't look useful (you want it, i can get it again, its too easy
to trigger, but it just didn't look very useful, there were about 5 function
names and a bunch of address)

my Stuff is
Slackware 10.2
Gware Rev E. (Gname 2.12.0)
X 6.8.2
Firefox 1.0.7


if i need to try with a newer version or something, i can if it cannot be reproduced

the php script used to trigger the error is below, if any develooper does not
have a server to test this with, just contact me and i will set it up

---Begin PHP --
<?php
session_start();


//store thr current stuff
$new_stuff = serialize(array($_REQUEST, $_SERVER));
$new_stuff = base64_encode($new_stuff);

if($_GET['start']) {
	$_SESSION['hello_world']=1;
	?><script language="javascript">
		location.href="test-here.php?count=1";
	</script><?
} else {
	if($_SESSION['hello_world']) {
		//$_GET['count'] = $_GET['count'] + 1;
		?><script language="javascript">
		location.href="test-here.php?count=<? echo $_GET['count']+1; echo
"&kh=$new_stuff" ?>";
	</script><?
	} else {
		echo "Session stopped after ".$_GET['count']." reloads!";
	}
}

?><br /><form method="POST" action="<? echo $_SERVER['php_self'];
?>?start=1"><input type="submit" value="Start Counter Again"></form>


---End PHP --

I could not reproduce this problem using firefox 1.5.0.2.
Is someone still able to reproduce this problem using a current version of xorg?

No crash for me now. Some display artifacts, but no crash. 

Lots of people, including myself, are finding that X crashes when using eclipse
when long strings are rendered.

I cannot reproduce the effect with the submitted URL.  However, this URL on MY
SITE crashes X every time, but only in Firefox 1.5.0.6 (32 bit).
