Subject: Segmentation fault on aircrack

Date: Mon, 13 Dec 2004 10:44:29 +0100

Package: aircrack
Version: 2.1-1

Error:
# aircrack Kismet-Dec-04-2004-15.dump
Opening pcap file Kismet-Dec-04-2004-15.dump
Segmentation fault


I've tried the same pcap file on a Ubuntu 32bit and the program starts. 


Accordingly with program author, I replaced
   if( fread( &pfh, 1, n, f_cap ) != (size_t) n )
with
   if( fread( &pfh, 1, (size_t) n, f_cap ) != (size_t) n )

but didn't solve.
We couldn't go further because he hadn't a 64bit test machine.
Here's the debug I produced for him after the modification

(gdb) run

This patch should do it for 64bits. At least it works here.
