Status: RESOLVED DUPLICATE of bug 138436

Text Zoom freezes the browser for a few seconds on complex pages, while it
didn't with mozilla 0.9.9

Confirm it happens on linux with mozilla r.0rc1 Gecko/20020417.
Dont know about win32 yet.

Comment 2

[Markus Hübner]

Works with build 2002041803 on win-xp.

Comment 3

[Daniel Bachran]

Works for me. At least I only get around 1sec delay on rather complex pages
(e.g. slashdot, www.spiegel.de), using 1.0rc1 on w2k.

Comment 4

[Håkan Waara]

We need a good testcase here that everyone will freeze on. Are there any extreme
cases where this will be visible for most users (even with fast computers) ?

This URL takes mozilla over 30 seconds on my 1GHz (CPU-intensive, RAM usage
unchanging): http://www.wincustomize.com/news_comments_full.asp?NewsID=765

This is build 2002041617 (1.0.0 branch).

First, I should correct myself: it definitely takes more than a minute or two on
the page I mentioned.

I ran a debug build from CVS (6pm EST, 15 April -- 2002041518; no specific
branch) and kill -SEGV'ed it about 10 seconds into the freeze to force a core
dump.  GDB cannot produce a complete backtrace: it gets to #267 and is killed. 
I'm attaching the whole of what I got (~61KiB) because I can't make enough sense
of it to know what could be cut out.

Bug 138436 seems similar to this (I got the URL from a Mozillazine comment).

Attachment: Stack trace of debug build showing lots of recursion

I snipped out all the symbol loading messages to reduce clutter
