直接の原因はunsafeなメソッドをsafeメソッドにしたこと
unsafeのsafe wrapperの質は大事
今のコードもunsafeの使い方が怪しくて信頼できない

fn get_release_unchecked_mut(&mut self, index: usize) -> &mut UntypedValue {
debug_assert!(index < self.capacity());
// Safety: This is safe since all wasmi bytecode has been validated
// during translation and therefore cannot result in out of
// bounds accesses.
unsafe { self.entries.get_unchecked_mut(index) }
}
