@dblaikie, you //did// reproduce the issue with the members. Both entries have
DW_AT_decl_line 2 and DW_AT_data_member_location 0 (the second entry should
indicate DW_AT_decl_line 3 and DW_AT_data_member_location 4):

As for the block-scope case, I am still able to reproduce the issue (and also
your result that does not exhibit the issue). The key seems to be having the
`_`s on the same line.
