Description
To reproduce:
using Distributed
addprocs(4)
using SharedArrays
matrix = SharedArray{ComplexF64}(10, 20, 30)
remotecall_fetch(() -> reshape(matrix, (100, :)), 2)The error is
ERROR: On worker 2:
MethodError: Cannot `convert` an object of type RemoteException to an object of type Matrix{ComplexF64}
