Dear Bowenshi,
> Thanks for your advice! I update my test script, now it can 100% reproduce problem in my computer.
Thanks for updates. Note that even if I used the updated script in my environment (HEAD, 2cf41cd30),
I could not perfectly reproduce the issue. The publisher rarely crashed and output the core-file.
The failed assertion was same as you reported firstly[1], not newer one.
