    Fortran: Cray pointer comparison wrongly optimized away [PR106692]

            PR fortran/106692

    gcc/fortran/ChangeLog:

            * trans-expr.cc (gfc_conv_expr_op): Inhibit excessive optimization
            of Cray pointers by treating them as volatile in comparisons.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/cray_pointers_13.f90: New test.

    (cherry picked from commit c7754a2fb2e60987524947fe189f3ffac035ea1d)
