I can reproduce this bug here under the MacPorts gnutar build of tar 1.29.
Normally, the default LANG for the system bash is set to en_US.UTF-8 such
that...

gnutar -zcvf test_data.tar.gz test_data

works fine. If I unset LANG on darwin15, I see the hang...

$ gnutar -zcvf test_data.tar.gz test_data
test_data/
test_data/.noe.tbl.swp
test_data/dihedral.tbl
test_data/file.nam
test_data/io.mc
test_data/noe.tbl
gnutar: test_data.tar.gz: Cannot write: Broken pipe
gnutar: Child died with signal 11
gnutar: Error is not recoverable: exiting now

This issue doesn't seem to exist for tar 1.26 on x86_64-apple-darwin15.
