 When you run 'error', it shows the usual stack trace.  When you enable
 profiling with the -prof flag to ghc, and you run 'error', it shows the
 usual stack trace plus an additional prof-specific stack trace.

 When you run 'errorWithoutStackTrace' with profiling enabled, it strips
 the usual stack trace of 'error', but still displays the prof-specific
 stack trace.
