This is very odd. It's failing very, very early in the runtime (right when the background scavenger is spinning up) trying to allocate a timer. And the problem seems to be that newobject has a nil type parameter? I'm not even sure how that can happen.

ianlancetaylor commented 5 years ago

The type parameter passed to newobject is 0x92d1a0. The 0x0 is the result parameter. The addr=0x0 printed at the start of the backtrace is meaningless, as this is not a fault signal, it is a trap signal. The trap signal does not set the address field (sigcode1) on Plan 9.

But that said I have no idea why the binary would get a trap signal. I don't know enough about Plan 9 to know what might cause that. If this happened only once I'm inclined to ignore it.

Not sure if this is related, but cmd/vet crashed from a trap signal in a trybot run:
