From bf800bbf28d6cf43272620697573ab3e02032b63 Mon Sep 17 00:00:00 2001 From: hank Date: Wed, 3 Aug 2011 10:52:34 +1000 Subject: [PATCH] The parameter's origin type is long. On an i386 architecture, it can easily be larger than 0x80000000, causing this function to convert it to a sign-extended u64 type. Change the type to unsigned long so we get the correct result.
