    More fixes for memory access errors when running readelf on fuzzed
binaries.

        PR binutils/17531
        * dwarf.c (process_debug_info): Check for abbrev_base being larger
        than the section size.
        (process_cu_tu_index): Use xcalloc2 to allocate the CU and TU
        arrays.
        (xcalloc2): New function.  Like xcalloc, but checks for overflow.
        * dwarf.h (xcalloc2): Prototype.
