# Description:
# A badly formed object range parameter passed to zdb -dd should
# return an error.
#
# Strategy:
# 1. Create a pool
# 2. Run zdb -dd with assorted invalid object range arguments and
#    confirm it fails as expected
# 3. Run zdb -dd with an invalid object identifier and
#    confirm it fails as expected
