Error messages in 4.3: "expectedFence"...?

Unity Engine
1

Hello, I’m starting to use 4.3 and so far it’s working nicely (my huge project was converted fine, although it took 25mn). But I’m seeing a lot of errors popping up in the console complaining about “fence”. And I don’t know what that is. Can anybody help please?

You find the same issue in here:

I am getting this error message as well. But it doesn’t seem to have negative effects on the project.
