    PR22047, Heap out of bounds read in parse_comp_unit

    Like the PR22230 fix, we can allocate a buffer with an extra byte
    rather than letting bfd_simple_get_relocated_section_contents malloc
    and return a buffer.  Much better than allocating another buffer
    afterwards.

        PR 22047
        * dwarf2.c (read_section): Allocate buffer with extra byte for
        bfd_simple_get_relocated_section_contents rather than copying
        afterwards.
