I'm having a problem extracting a tar that contains the device node
/dev/ptmx (character device 5,2).  Tar creates the file, then segfaults.
I originally detected this with a rather large tar created on a linux
machine.  However, this can be re-produced entirely on cygwin as in the
following transcript.  Other device nodes seem to work OK.
