runc list failure

[rajasec]

Started the fedora container with docker version
Server Version: 17.03.1-ce

In another directory, I have used the latest master runc to run an ubuntu container.
When I tried to do runc list
load container cee99b245cd41f1aa266dfab142acd5d9cecfad8e30dec17a1a8ac92add00a16: json: cannot unmarshal string into Go struct field State.init_process_start of type uint64

This is because state.json of fedora container created by docker is having string type for field init_process_start. Recently in runc it got changed to uint64 as per this commit

Yeah, that's because you have two runc versions that are sharing incompatible state. That's not really a supported configuration (though we should be more friendly about not bailing when an error occurs).
