    Fix more potential seg-faults in gprof.

        PR gprof/20499
        * corefile.c (num_of_syms_in): Return an unsigned int.
        (core_create_syms_from): Catch a possible integer overflow
        computing the argument to xmalloc.  Also allow for the possibility
        that an integer overflow in num_of_syms_in means that less space
        has been allocated than expected.
