[Haskell-cafe] Cannot read a large integer on linux

[Artyom Kazak]

Right, it was fixed in GHC 7.4.2.

hackage.haskell.org/trac/ghc/ticket/5688

The trouble with old behaviour was that it had been creating a security
breach (anybody could pass "1e100000000000" where an Integer was expected
and cause a segmentation fault).
