    Sanity check section size in bfd_init_section_compress_status
    
    This function doesn't just initialise for compression, it actually
    compresses.  This patch sanity checks section size before allocating
    buffers for the uncompressed contents.
    
            * compress.c (bfd_init_section_compress_status): Sanity check
            section size.
