bn254-mpc setup issue

[cxmqq333]

when I run the TestSetupCircuit method of bn254/mpcsetup/setup_test.go (master branch or v0.10.0 ）it is ok.
But when I change the circuit to the github Example CubicCircuit and run , there is always a err on call groth16.Prove:
Error: Received unexpected error:
len(points) != len(scalars)

It may be a bug - we have open issue for MPC key generation open #1180. Do the examples work when the keys are generating using trusted setup (without MPC)?

[cxmqq333]

yes, it works when using trusted setup (without MPC). It may be the power is too big for the curcuit.

Alright - I guess we would have to look into MPC. We have been a bit busy with Linea open-sourcing lately, but it is definitely important to resolve.
