Subject: Signed Unsigned multiplication in io.c
Date: Thu, 5 Jul 2007 15:07:35 +0530 (IST)	[thread overview]
Message-ID: <41876.172.16.0.34.1183628255.squirrel@webmail.calsoftinc.com> (raw)

There is signed multiplication assigned to unsigned ei.addr in io.c.
This causes wrong addresses for big multiplication.This patch solves the
problem.
