Comment (by rwbarton):

 I tried to investigate this, but Agda has a bunch of upper bounds that
 rule out building with 7.10, and with `--allow-newer`, I got an error
 about `No instance for (GHC.Generics.Generic (Ptr a))` and gave up. How
 did you manage to build Agda with 7.10 in the first place?
