commit 041830e03cca866f12be18198898139e558ad31e
Author: Nick Clifton <address@hidden>
Date:   Fri Nov 14 12:30:00 2014 +0000

    More fixes for invalid memory accesses triggered by corrupt binaries.

        PR binutils/17512
        * dwarf.c (get_encoded_value): Add an 'end' parameter.  Change the
        'data' parameter to a double pointer and return the updated value.
        (decode_location_expression): Update call to get_encoded_value.
        (frame_need_space): Handle the case where one or both of the
        mallocs fails.
        (read_cie): Initialise the cie pointer, even if the read fails.
        (display_debug_frames): Warn if the calculated block_end is before
        the start of the block.  Break the loop if the CIE could not be
        read.  Update call to get_encoded_value.  Warn if the read CFA
        expressions are too big.

        * ieee.c (ieee_archive_p) Skip processing if no bytes are read at
        all.
        (ieee_object_p): Likewise.
