# This test verifies that: if a parent die(DW_TAG_subprogram) has zero
# length address range and has a child with normal address range then
# the "DIE address ranges are not contained in its parent's ranges"
# error is reported. It also checks that if a parent die has zero
# length address range and has children with overlapped addresses
# then the error "DIEs have overlapping address ranges" is reported.
