Can you please provide a runnable sample for debugging? I cannot find out any issue from this call stack. It may be a bug in this package; It can also be an issue from caller which provides an invalid element pointer.

As I cannot analyze this without a sample, I close this issue for lack of enough information. @laplaceyang feels free to reopen this issue if you can provide a sample.
