read for StdGen fails for arbitrary string
|Reported by:||guest||Owned by:|
|Type of failure:||Difficulty:||Unknown|
|Test Case:||Blocked By:|
According to the docs for StdGen?:
- It guarantees to succeed on any string.
- It guarantees to consume only a finite portion of the string.
- Different argument strings are likely to result in different results."
Here's what happens on my system:
GHCi, version 6.8.3: http://www.haskell.org/ghc/ :? for help
