Is tar Broken In 10.3-STABLE?

Tue Jul 5 16:59:31 UTC 2016

I just upgraded to r302342 today to verify a problem I saw 
after a 10.3-STABLE upgrade yesterday.  Upgrade was 
accomplished via makeworld/kernel & installworld/kernel.

When using tar with the -T argument to provide a list 
of backup sources, it blows out with the following 
error if a source in the file list is missing:

   tar: INTERNAL ERROR: Function 'archive_read_disk_open' invoked with archive structure in state 'header', should be in state 'new/closed': Unknown error: -1

In the past, tar would make some noise if it was asked
to copy a nonexistent file or directory, but it would 
continue the remainder of the archive operation.

Thoughts?
