   6 ## Check that we parse the LOH & match it to its referent sections correctly,
   7 ## even when there are other subsections that don't get parsed as regular
   8 ## sections. (We would previously segfault.)
   9 ## __debug_info is one such section that gets special-case handling.

  16 ## __StaticInit occurs after __debug_info in the input object file, so the
  17 ## LOH-matching code will have to "walk" past __debug_info while searching for
  18 ## __StaticInit. Thus this verifies that we can skip past __debug_info
  19 ## correctly.
