------- Comment #2 from drow at gcc dot gnu dot org 2010-04-04 15:45 ------- FYI, this patch also fixes a number of failures in cpexprs.exp in GDB. Testcase:
struct s { bool operator!= (s const& o) const { return false; } }; bool func (const struct s& arg, const struct s& right) { return arg != right; } The THIS argument of operator!= gets a valid type. The O argument gets the self-typedef, and produces a DW_TAG_const_type with no type argument. I'd say an assertion in modified_type_die after creating a new const or volatile DIE with sub_die == NULL would be appropriate, if it weren't for the ERROR_MARK handling... I don't know if we get here after errors. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43628
