GHC.Err.errorWithoutStackTrace produces stack trace when profiling enabled
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.
