--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
we don't elide inlined_function_outer_scope_p IIRC, so not sure why this would
happen?  But the flow of conditions is a bit odd:

   /* When not generating debug info we can eliminate info on unused
      variables.  */
   else if (!flag_auto_profile
            && debug_info_level == DINFO_LEVEL_NONE
            && !optinfo_wants_inlining_info_p ())
     {
       /* Even for -g0 don't prune outer scopes from inlined functions,
          otherwise late diagnostics from such functions will not be
          emitted or suppressed properly.  */
       if (inlined_function_outer_scope_p (scope))
         {
           gcc_assert (TREE_CODE (BLOCK_ORIGIN (scope)) == FUNCTION_DECL);
           unused = false;
         }
     }
   else if (BLOCK_VARS (scope) || BLOCK_NUM_NONLOCALIZED_VARS (scope))
     unused = false;
   /* See if this block is important for representation of inlined
      function.  Inlined functions are always represented by block
      with block_ultimate_origin being set to FUNCTION_DECL and
      DECL_SOURCE_LOCATION set, unless they expand to nothing...  */
   else if (inlined_function_outer_scope_p (scope))
     unused = false;
