+Files over 4 Gig in size encountered an error resulting in an unsuccessful copy as
+per (upstream) Bug Request ID: 1110812.
+
+The assignment 'len = job->basis_len' sometimes overflows. Made changes so that
+assignment is done only when appropriate.
+
+rs_mdfour variables B and C were observed to overflow their 'int' definition.
+This has been changed to 'unsigned int', which is now consistent with like coding
+in the openssl package.
