    Fortran: fix bounds check for copying of class expressions [PR106945]

    In the bounds check for copying of class expressions, the number of
elements
    determined from a descriptor, returned as type gfc_array_index_type (i.=
e. a
    signed type), should be converted to the type of the passed element cou=
nt,
    which is of type size_type_node (i.e. unsigned), for use in comparisons.

    gcc/fortran/ChangeLog:

            PR fortran/106945
            * trans-expr.cc (gfc_copy_class_to_class): Convert element coun=
ts
in
            bounds check to common type for comparison.

    gcc/testsuite/ChangeLog:

            PR fortran/106945
            * gfortran.dg/pr106945.f90: New test.
