Hi Oliver,

Sorry for late, our servers have been down for a few days and we just managed to fix it today.

We retested the patch you provided, but we found that the issue still exists, but may be somewhat different from the call trace from the previous issue. I have provided a screenshot in diff form and the full call trace log in the attachment.

Thanks,
Kun Hu
