+
+	* Backport #1524 [ruby-core:23567]; lib/ostrct.rb (OpenStruct@new_ostruct_member): check if it's; also a little code cleanup to do a few things more efficiently. Tests adjusted accordingly.
+
+	* test/ruby/test_file_exhaustive.rb: Fixed a mistake in the monkey patched String#start_with? method required by the test suite.
