In this case we left u.str with garbage (from u.val) which then led to a segfault when attempting to access the string. Fix that by clearing u.str. The patch also adds missing sanity checks in the recently committed read_indexed_address and read_indexed_string functions. PR 29230 * dwarf2.c (read_indexed_address): Return uint64_t. Sanity check idx. (read_indexed_string): Use uint64_t for str_offset. Sanity check idx. (read_attribute_value): Clear u.str for indexed string forms when DW_AT_str_offsets_base is not yet read or missing. -- You are receiving this mail because: You are on the CC list for the bug.
