This test failed because the Bats internals are violating one of the
constraints imposed by:

--------
$(<"$FIXTURE_ROOT/unofficial_bash_strict_mode.bash")
--------

See:
- https://github.com/sstephenson/bats/issues/171
- http://redsymbol.net/articles/unofficial-bash-strict-mode/

If there is no error output from the test fixture, run the following to
debug the problem:

  $ SHELLOPTS=nounset bats $RELATIVE_FIXTURE_ROOT/unofficial_bash_strict_mode.bats

If there's no error output even with this command, make sure you're using the
latest version of Bash, as versions before 4.1-alpha may not produce any error
output for unset variable accesses.

If there's no output even when running the latest Bash, the problem may reside
in the DEBUG trap handler. A particularly sneaky issue is that in Bash before
4.1-alpha, an expansion of an empty array, e.g. "\${FOO[@]}", is considered
an unset variable access. The solution is to add a size check before the
expansion, e.g. [[ "\${#FOO[@]}" -ne 0 ]].
