        PR tree-optimization/45580
        * tree-ssa-propagate.c (substitute_and_fold): Always replace
        regular uses.
        * gimple-fold.c (gimple_fold_obj_type_ref): For a BINFO without
        virtuals fold the call into a regular indirect one.

        * g++.dg/torture/pr45580.C: New testcase.
