I tested on Windows XP with IE6, and do not crash..
IE alert me with an error "Out of stack space" / "Stack overflow at line: 0"
but do not use 1oo% cpu or die..

After a few minutes testing it seems this does not only effect Internet

a bit OT, but anyway, I also checked this and
Konqeror 3.0.0 hogs the CPU, but there was no segfault, the same effect
(100% CPU utilization) is done by simply this:
<html><head></head>
<script language="JAVASCRIPT">
function foo() {
foo();
}
</script>
<input type="button" onClick="foo();" value="SMASH!"></input>
</html>

This situation is handled by both IE and Mozilla 1.0rc1 (no hogs there)


   I get a hard crash in Konqueror from KDE 3.0.0.  We're looking into it
right now.  It's rather obvious what is wrong, but the best solution needs
to
be worked out by the JS developers.
