Hi, It seems that the problem is the site is using GHC 6.6.1, and something was broken at the time (I have not looked into what that is). Here are the outputs that I get for the little example on the site that you posted:

GHC 6.10.3 and C++:

03 10103538 2222 1233 6160 0141 1 03 10103538 2222 1233 6160 0142 1 30 10103538 2222 1233 6160 0141 2 30 10103538 2222 1233 6160 0142 2

30 10103538 2222 1233 6160 0142 1 30 10103538 2222 1233 6160 0143 1 30 10103538 2222 1233 6160 0144 1 30 10103538 2222 1233 6160 0145 1 30 10103538 2222 1233 6160 0146 1

With GHC 6.6.1: 03 10103538 2222 1233 6160 0141 1 03 10103538 2222 1233 6160 0142 1 30 10103538 2222 1233 6160 0141 2 30 10103538 2222 1233 6160 0142 2

30 10103538 2222 1233 6160 0142 1 30 10103538 2222 1233 6160 0143 1 30 10103538 2222 1233 6160 0145 1 30 10103538 2222 1233 6160 0146 1

Note that in the second test case one line is missing, the one ending in 44.

Hi Iavor, Sweet, it makes a lot of sense. I haven't tried to run this with ghc-6.6.1, though. Thank you for doing this. Just for curiosity I'll try to find out what exactly fails under 6.6.1, just in case anyone else run into the problem in future (as I don't think they will upgrade the ghc any time soon). I'll eventually ask them to upgrade the ghc version. Any recommendation about which version should I ask for?
