so confused... I have asked one of my friends to compile this code. And he also got an fail
It seems this bug only occurs on a 32-bit version ghc update: my friends said he changes the decode line into a ugly way: > let x = decode $(C.pack. C.unpack) au :: Maybe AuctionInfo then he got an ok but i did so, also fail... Subject: Re: [Haskell-cafe] a bug of 32bit ghc on mac ? From: hutch-li...@recursive.ca Date: Wed, 1 May 2013 05:43:46 -0400 CC: haskell-cafe@haskell.org To: s...@live.com I compiled and ran it a few hundred times in a script with no failures. I've got the same version of GHC on OS X 10.8.3. BTW, it's not just Yesod that has that bug you mentioned in the 64-bit version.

I just want to make sure is this my bug or a bug of ghc p.s. the reason using 32bit ghc is yesod, which has met another bug on 64bit mac ghc :( thanks sray _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
