avoid reading uninitialized variable
autoload_reset() can read this state.result. Because autoload_reset
is a function passed to rb_ensure, there is a chance when an
execption raises before actually filling this memory region.
test/ruby/test_defined.rb:test_autoload_noload is one of such case.
Found using memory sanitizer.
