Subject: Pack, then unpack total in debug_split_print.
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=d949db2e03d3a9a76b6dd604e8871fc299712077;p=working%2FSIPServer.git

Pack, then unpack total in debug_split_print.

The checksum needs to be a 16bit value, so we pack, then unpack the
checksum total in debug_split_print to guarantee that.  Some longer
messages have generated 32-bit checksums.
