My guess is he's redirecting stdout and stderr to the same file, and stderr
happens to get flushed by the Haskell runtime before stdout (possibly
because a flush is performed regardless when an exception is printed). It
is, as you note, not really relevant to the actual logic error leading to
the exception.
