I attached a minimal example that you can run with: {{{ $ ghc-7.10.1.20150630 -O RealRing.hs [1 of 1] Compiling RealRing ( RealRing.hs, RealRing.o )
RealRing.hs:11:6: Warning: Rule "NP.roundSimple :: a -> Word" may never fire because ‘roundSimple’ might inline first Probable fix: add an INLINE[n] or NOINLINE[n] pragma on ‘roundSimple’ ^C }}} Thanks! That fails for me also. It works if I compile without the -O
