	Simplifier ticks exhausted
    When trying UnfoldingDone base:GHC.Base.returnIO1{v r5g} [gid]
    To increase the limit, use -fsimpl-tick-factor=N (default 100)
    If you need to do this, let GHC HQ know, and what factor you needed
    To see detailed counts use -ddump-simpl-stats
    Total ticks: 27960
