The process hierarchy (from top to bottom) is:
  gmake check
  gmake check-am
  gmake check-TESTS
  /bin/sh -c set +e; bases='t/file.sh.log t/file-node.sh.log

  gmake test-suite.log TEST_LOGS=t/file.sh.log t/file-node.sh.log 
t/file-nodes.sh.log t/file-node-with-dot.sh.log t/file-index.sh
  /bin/sh -c p='t/malformed-split.sh'; \^Jb='t/malformed-split.sh'; \^Jcase $- 
in *e*) set +e;; esac; srcdirstrip=`echo "../../in
  /bin/sh ../../build-aux/test-driver --test-name t/malformed-split.sh

pseudotty: getting pty master fd

pseudotty: getting file name of slave device...
pseudotty: /dev/pts/8
pseudotty: opening slave device

Adding more debugging statements, I see that it hangs in the line
  if (!isatty (slave))

Commenting out this line fixes the issue; all 85 tests in this
directory then pass.

Note: The code in gnulib/lib/openpty.c, which is tested on many platforms,
does not contain an isatty() call in this place.
