No check was performed and the value was assumed non null. Path conversion returned an empty path for "Self" due to a hack in generics Self injection that prevented any "Self!" macro from beeing recognized correctly. gcc/rust/ChangeLog: * parse/rust-parse-impl.h (Parser::parse_stmt_or_expr): Add null check on parse_macro_invocation_partial call. * ast/rust-path.cc (Path::convert_to_simple_path): Do not exclude capitalized "Self". gcc/testsuite/ChangeLog: * rust/compile/issue-3974.rs: New test.
