Gwyn Connor pointed out a sprintf() abuse...

When log entries are generated, we're passing outbuf both as buffer and as
a source of data.  Behaviour is undefined on some systems, notably including
Gentoo Linux.

Change:  Make sure there are buffers for the date + process, fill them, and
reference them.
