Subject: w3m: crash on <hr width=4358144>

Date: Fri, 25 Jul 2008 00:27:38 +0100

[Message part 1 (text/plain, inline)]

Package: w3m
Version: 0.5.2-2+b1
Severity: normal

Another crash, observable on seemingly inoffensive web pages:

 w3m http://mywebpages.comcast.net/boydmayberry/Bunnies.html
 GC Warning: Repeated allocation of very large block (appr. size 31006720):
         May lead to memory leak and poor performance.
 GC Warning: Repeated allocation of very large block (appr. size 31006720):
         May lead to memory leak and poor performance.
 [etc until it segfaults]

All that's needed to replicate the effect is a horizontal rule with
a width above 4,358,143, as in the attached file.
