:abandon in an exception breakpoint can lead ghci to freeze later
An example:
Prelude> :set -fbreak-on-exception
Prelude> error "an error"
Stopped at <exception thrown>
_exception :: e = GHC.IOBase.ErrorCall ('a' : _)
unable to list source for <exception thrown>
[<exception thrown>] Prelude> :abandon
Prelude> () -- whatever we do here, ghci freezes
()
