Thanks for checking so far.  Next would be test 38.  One way
to investigate that would be to put the following shell script
into a file "test-scarce", and then running the shell command
"truss -f -o tr sh test-scarce".  Please arrange to have
the two "tar" invocations be the most-recent "tar"
that you built.

mkdir gnu || exit
cd gnu || exit

export TEST_TAR_FORMAT
