        PR 24798
        * dwarf.c (process_cu_tu_index): Avoid integer overflow on 64-bit
        systems by casting ncols and nslots expressions to size_t.  Display
        number of columns and slots before giving up due to buffer overflow.
        Use %u to display unsigned ints.  Perform more pointer wrap tests.
