238394 - Floating Point Exception using an invalid? font

Status: RESOLVED DUPLICATE of bug 180309

(SeaMonkey :: General, defect)

Description

[Christian Fertig]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de-AT; rv:1.6) Gecko/20040114
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; de-AT; rv:1.6) Gecko/20040114

I've got an example to crash mozilla and latest firefox using an invalid font
configuration on my system. 

I'm using my windows ttf-fonts with xfs 

rpm -qf /usr/X11R6/bin/xfs
XFree86-4.3.0.1-46

I've got a symlink from the windows-fonts directory to my ttf-directory. There
are some fonts inside, which aren't (imho) valid truetype fonts. In this case:
8514sys.fon. Perhaps this problem isn't mozilla related, I don't know exactly,
how the font handling is done in the linux port. Perhaps xfs should not report
the font. But I think mozilla shouldn't crash and use a valid font instead.



Reproducible: Always
Steps to Reproduce:
1. Use the 8514sys.fon as truetype with xfs
2. Try the minimum example

Actual Results:  
sigfpe (Floating Point Exception)

Expected Results:  
Use some valid font.
