  14 # In this test case the ExtraDef symbol below will be overridden by a strong
  15 # def in MachO_strong_defs_extra.s. This will leave main (with alignment 16,
  16 # alignment offset 4) as the only block in __TEXT,__text. The testcase ensures
  17 # that the debugging support plugin doesn't crash or throw an error in this
  18 # case.
