Crash for me too!  I get an "violent access" error in Windows from "PSM". On a
related note: this happens for me when I try to log in at sourceforge.net with
SSL enabled.

build: 2000111808

wfm linux build 2000-11-18-06 but _does_ freeze for a while as it lays out the
page.

So it looks frozen, but given a bit of time starts responding again...

I don't recall how long I waited for it to "finish," but it seemed
hung to me.  If it's not hung, then whatever code it is that takes
so long to execute needs to be sped up a lot.  Please don't mark as
fixed until something is done here - the average Joe (that's me)
won't understand...

psm issue - over to crypto

Comment 6

[Boris Zbarsky [:bzbarsky]]

I very much doubt this is a psm issue.  I saved the page locally and opened it
as an http url, and it took just as long.  I am guessing that the primary
culprit here is the creation and filling of about 1900 Array objects in the
javascript.

This may not be the problem reporter is seeing, of course...  I'll attach a copy
of the source to this bug.  [e-mail], could you please check whether
the browser freezes for you on the attachment too (at an http:// url)?  Thanks.

Ok, a better bug report...

Same behavior from the Mandrake server, from the attachment, or as a
local file.

Yes, it eventually un-hangs when rendering the page.  However, I can
pretty reliably still reproduce a hang.  After the page renders, click
on "Linux Mandrake", then "7.1".  At this point, browser sometimes hangs.
If not, try to scroll the packages list.  It always hangs at this point
or earlier.  More info: the packages scroll list half-redraws before
it hangs.  Also, if I switch away from Mozilla and come back, the scroll
bars partially repaint on the page, but nothing else.  Also, when it's
"hung", CPU goes to 100% utilization.

The perf problems on bugzilla's query.cgi are tracked by bug 27233, and the 
fact that you can't interact with the window while the page is frozen is bug 
30942.  Håkan Waara also mentioned a psm crash on the mandrake page, but I'm 
not seeing the crash on Win98 using the same Mozilla build and PSM 1.3 
(javascript:crypto.version).

junruh: so you're treating the crash as wfm?

Comment 12

[John Unruh]

No, it looks to me like a dupe of bug 27233. If you disagree, please reopen this 
bug.
