You have removed most of the interesting parts of the stack trace.

Given the information you have provided there is no way for us to help

exhibit the same behaviour.

It is most likely the input - lots of people do manage to send traps.

Could you please elaborate on the input, "<optimized out>" ain't exactly
helpful.

Nope, I have never seen one there.
