        * cgraphunit.c (cgraph_emit_thunks): Emit thunks only for
        reachable nodes.
        (cgraph_finalize_compilation_unit): Compute reachability
        before emitting thunks.  Properly process aliases before
        possibly removing unreachable nodes.

        * g++.dg/torture/pr41257-2.C: New testcase.
