    Fortran: error recovery from calculation of storage size of a symbol [PR103504]
    
    gcc/fortran/ChangeLog:
    
            PR fortran/103504
            * interface.c (get_sym_storage_size): Array bounds and character
            length can only be of integer type.
    
    gcc/testsuite/ChangeLog:
    
            PR fortran/103504
            * gfortran.dg/pr103504.f90: New test.
    
    (cherry picked from commit 600956c81c784f4a0cc9d10f6e03e01847afd961)
