I would asume that a lot of tar archives created with star -cP
will look this way.

The option -P has been introduced into star around 1986 in order to
help better dealing with QIC tapes that have more than one file mark
anr more than tape file.

A tar implementation should only write a warning/error message 
only when the byte count is not a multiple of 512.

BTW: a lot of RPM files contain broken CPIO archives (most likely
created with GNU software) that are not a multiple of 512 and thus
rejected by star.
