"""Basic test of the frozen module (source is in Python/frozen.c)."""
# The Python/frozen.c source code contains a marshalled Python module
# and therefore depends on the marshal format as well as the bytecode
# format. If those formats have been changed then frozen.c needs to be
# updated.
#
# The test_importlib also tests this module but because those tests
# are much more complicated, it might be unclear why they are failing.
# Invalid marshalled data in frozen.c could case the interpreter to
# crash when __hello__ is imported.
