        * tree-inline.c (copy_edges_for_bb): Don't split bb if a stmt that
        newly needs to end a bb is followed by debug stmts, instead return
        true from the function at the end.
        (maybe_move_debug_stmts_to_successors): New function.
        (copy_cfg_body): Call it if copy_edges_for_bb returned true.

        * g++.dg/debug/pr44182.C: New test.
