Description:
Gcp pointer is initialised with call to last.
This can fail and return a null pointer which leads to crash when the pointer is used
to setup EVENT_REP signal.

How to repeat:
test_event -r 5000 -n Bug30780 T1
At least fails on Mac OS X with ARM

Suggested fix:
Probably set to 0 if pointer is nullptr, possibly better solution exists.

The failing method is start_resend
