[Bug-tar] Basic testing needed.....

[Joerg Schilling]

Hi,

did you do some basic testing before you decided to publish
a new release?

/tmp/tar-1.13.90/src/tar -tvf  not_a_tar_file 
/tmp/tar-1.13.90/src/tar: Record size = 2 blocks
/tmp/tar-1.13.90/src/tar: This does not look like a tar archive
/tmp/tar-1.13.90/src/tar: Skipping to next header

Segmentation Fault - core dumped

adb  /tmp/tar-1.13.90/src/tar core
core file = core -- program ``/tmp/tar-1.13.90/src/tar'' on platform i86pc
