------------------------------+---------------------------------------------
This is with GHC 7.4.1, running on Linux, 32 bits:
{{{
Prelude> maxBound :: Int
2147483647
Prelude> :m Data.Int
Prelude Data.Int> [5 `div` (minBound+k::Int64) | k <- [0 .. 10]]
[0,0,1,1,1,-1,-1,-1,-1,-1,-1]
}}}
Expected value: Last expression should evaluate to:
{{{
[-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1]
}}}
