    at src/common/hashtable/src/container.rs:210

impl<T, const N: usize, A: Allocator> Drop for StackContainer<T, N, A> {
    fn drop(&mut self) {
210->    if !self.ptr.is_null() {
            unsafe {
                self.allocator.deallocate(
                    NonNull::new(self.ptr).unwrap().cast(),
                    Layout::array::<T>(self.len).unwrap(),
                );
            }
        }
    }
}
