Comment(by erikd): I've add -ddump-rule-rewrites to the command line and the last rule firing before it seems to hang with 100% CPU usage is: {{{ Rule fired Rule: Class op + Before: GHC.Num.+ (TYPE GHC.Types.Int) GHC.Num.$fNumInt i1_a2tL (GHC.Types.I# 1) After: GHC.Num.$fNumInt_$c+ Cont: Stop[BoringCtxt] GHC.Types.Int }}} Is this the rule that is hanging or is the next one that has not yet been displayed? -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7553#comment:1> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
