BuildID:    20020610

Crashes on supplied page (not sure yet if it is the only one, but probably
not)when "ctrl -" used to shrink fonts, excessive "ctrl +" might have the same
effect. 
Mozilla outputs this message: /usr/local/mozilla/run-mozilla.sh: line 72: 18661
Floating point exception$prog ${1+"$@"}
Could also be a bug in gtk/gdk libraries.

Reproducible: Always
Steps to Reproduce:
1.Go to page http://www.coffeehaus.com/favorites.html or any other one maybe?
2.Press "ctrl -"
3.repeat 2 until crash

Actual Results:  Crash and:
Mozilla outputs this message: /usr/local/mozilla/run-mozilla.sh: line 72: 18661
Floating point exception$prog ${1+"$@"}

Expected Results:  Nothing?

Comment 1

[David Caplan]

Mozilla is NOT affected by using "ctrl +"

Reporter:
Do you use a mozilla.org build or do you compiled yourself or do you use a
distributed build ?

Can you add a talkback ID of that crash ?

Comment 3

[David Caplan]

If i can remember correctly, this is the mozillal 1.1a build.
I've never posted a bug before :) How do I get a talkback id. I actually
installed mozilla without talkback enabled (i think)

Comment 4

[Matthias Versen [:Matti]]

You need a talkback enabled build...
After talkback submitted the crash run mozilla/components/talkback to get the ID.

You should be able to install talkback in your existing build if you use a
mozilla.org not rpm based build.
Be sure that software installation and Javascript is enabled and click on this link:
ftp://ftp.mozilla.org/pub/mozilla/releases/mozilla1.1a/linux-xpi/talkback.xpi

I'm not sure if this is important, but here is the all the data from the crash:

Comment 9

[kill this account]

could you try setting the environment variable NS_FONT_DEBUG=FFF, capture moz's
output, and attach it to this bug?

Comment 10

[David Caplan]

There was no output...
or i missed something :)

Comment 11

[kill this account]

it should be hundereds/thousands of lines. here is a typical output:
attachment 89958 [details]

For csh

 setenv NS_FONT_DEBUGFFF

for sh/bash/ksh

 export NS_FONT_DEBUG=FFF

(Try running the env command to see if it is set)

Did you restart moz after setting it?

Comment 12

[ratman]

using moz1.1a on winme.  wfm.

reporter, what is your default font setup?

Comment 13

[David Caplan]

NS_FONT_DEBUG=FFF output is here -> http://david.ath.cx/ns_font_debug.txt

my default font setup is anti-aliased western adobe-new cent. schoolbk size 18
and by the way, it still crashes if i set a minumum font size. seems to be some
sort of overflow, if i hold "ctrl -".

I wonder if this is realted to bug 155175.

Do you build moz? If so could you try applying attachment 89876 [details] [diff] [review]?

Comment 15

[David Caplan]

i doubt it's related...
no i dont build it mozilla, it is version 1.1a - 20020610

Comment 16

[Bill Mason]

This bug may be related to or dup bug 155970.

Comment 17

[timeless]

evicting from b-g (should be in Browser:Fonts)

Comment 18

[Andrew Schultz]

bug 155175 and bug 155970 have both been fixed.  David, can you try a newer build?

layout==fonts?
