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.

hi all
it seems i have met some bug on a MAC 32bit GHC version 7.4.2
to make long stroy short, my code is about parse a json file using aeson here is my code http://pastebin.com/0VcVhdvX
and here is test data http://pastebin.com/PvtSvst5
and test steps save the code , and name it a.hs (or what you want) save the test data ,name it a.json (do not change its name) $ ghc a.hs -o a $ ./a
what i get from the output is "fail" and when i run the command below for a few times $ runghc a.hs i even got some ok and some fail mixed together
but i copy the code and compile it on my linux, everything goes fine, the output is "OK" i have run "uninstall-hs" and install a 64bit ghc, also goes fine
i delete one line randomly chosen from my test data , got an ok roll back ,delete another line, also an ok...
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 :(
