During the recent upgrade to PartitionedArrays.jl v0.3, I've had to limit the compatibility of the julia binaries to 0.13 and 0.15.
With any binary versions above that, errors occur (see for instance).

I am not currently 100% sure of what is causing the issue, but it is probably related to changes to the PETSc library. Hopefully it only involves a change in the tests, but it could be deeper. We should have a look at what is causing the issue and restore compatibility.
