# Tests that error is printed correctly when DW_AT_low_pc value is
# greater then a range entry.

# CHECK: 0x0000006e: adding range [0x0000000000000000-0x000000000000001f)
# CHECK-SAME: which has a base that is less than the function's low PC 0x0000000000000021.
# CHECK-SAME: Please file a bug and attach the file at the start of this error message
