I don't believe you ever did have a test case that would trip the lbound
check.  What was failing was the ARR_NDIM == 1 check.  If you were to
look at the array in gdb, the apparent value of the lbound would be
indeterminate because it's off the end of the allocated space for a
zero-D array.  But the code wouldn't be reaching that test.
