Work around problem in DWARF decoding library which can result in attempts to read arbitrary bytes as if they were an LEB128 encoded value.
* dwarf.c (skip_attr_bytes): Accept DWARF versions higher than 4
when processing the DW_FORM_ref_addr form.
Skip bytes in DW_FORM_block and DW_FORM_exprloc forms.
Handle DW_FORM_indirect.
(get_type_signedness): Allow a limited amount of recursion.
Do not attempt to decode types that use the DW_FORM_ref_addr form.
(read_and_display_attr_value): Do not attempt to decode types
that use the DW_FORM_ref_addr form.
