181068 - Mozilla freezes when starts printing [fixed by erasing the fastload file]

Status: VERIFIED DUPLICATE of bug 169777

(Core :: XUL, defect)

Description

[Aleksey Nogin]

Reproducible: today - 100%, but was working OK yesterday

As soon as I click on the "Print" button in the print dlg, Mozilla freezes with
100% CPU usage - it does not even get a chance to redraw the portion of the
window that was hidden by the print dialog. Freeze happens, no matter whether I
am trying to print directly or to a file. If printing to a file, the first 32768
bytes of the file get written out.

This is BuildID 2002111716 (trunk) compiled and running on Red Hat Linux 7.3.
The weird thing is that it was just printing fine yesterday (running exact same
binaries on the exact same machine) and I have no idea what have changed!

Trying it several times on several very different pages
(http://www.cs.caltech.edu,
http://bugzilla.mozilla.org/enter_bug.cgi?product=Browser,
http://www.lib.ru/ZELQZNY/head.txt_with-big-pictures.html) and attaching gdb
several times to each, I saw a bunch of very similar stack traces. The following
one was the most common (I saw it for each of the 3 URLs):

P.S. The only other "print freezing" bug that I could find is bug 77309
(presumably a plugin-related freeze), so I made sure to temporarily remove the
flash plugin (the only one I have installed) and this didn't make any difference
(none of the pages had any flash on them, but one of the things that did change
since yesterday was that I've upgraded the plugin, so I wanted to be sure it's
not related).

Comment 1

[Daniel Wang]

have you tried deleting the xul.fasl file form the mozilla directory?

Comment 2

[Aleksey Nogin]

Not yet. But you are right - this is very likely to be caused be it.

Comment 3

[Aleksey Nogin]

I was not able to reproduce it on the same machine, but just had it happen on a
different machine - BuildID 2002112018 commpiled (with xft) and running on Red
Hat Linux 8.0. The problem went away as soon as I removed the XUL.fasl file.

Comment 4

[Brendan Eich [:brendan]]

jrgm, are there dups of this?  Maybe the printing dialog (xul, I guess) is the
key to reproducibility.

If someone can make this happen under a debug build, please email me or get in
touch with me via irc.mozilla.org.
