@jhenderson  Thank you for pointing this out! Actually --verify complains about errors in both cases(with the fix and without the fix)  for the testcase from this review:

without this patch :

error: DIE has overlapping address ranges: [0x0000000000000000, 0x0000000000000006) and [0x0000000000000000, 0x0000000000000006)
error: DIEs have overlapping address ranges:
error: DIE has overlapping address ranges: [0x0000000000000000, 0x0000000000000006) and [0x0000000000000000, 0x0000000000000006)
error: DIEs have overlapping address ranges:

with this patch :

error: Invalid address range [0xfffffffffffffffe, 0x0000000000000004)
error: Invalid address range [0xfffffffffffffffe, 0x0000000000000004)
error: Invalid address range [0xfffffffffffffffe, 0x0000000000000004)
error: Invalid address range [0xfffffffffffffffe, 0x0000000000000004)

there is not any address range to which these debug_info sections relate.  This address range [0x0000000000000000, 0x0000000000000006) should probably also be reported by --verify since it less than image_base...

Probably, without eliminating broken debug_info there is no way to verify it without errors?
