    c++: decltype of capture proxy of ref [PR115504]

    The finish_decltype_type capture proxy handling added in r14-5330 was
    incorrectly stripping references in the type of the captured variable.

            PR c++/115504

    gcc/cp/ChangeLog:

            * semantics.cc (finish_decltype_type): Don't strip the reference
            type (if any) of a capture proxy's captured variable.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp1y/decltype-auto8.C: New test.
