#2525: maps created by Data.Map.fromAscList fail lookup on some keys present

{{{
import Data.Map
member "foo" $ fromAscList [("foo", True), ("bar", False)]
}}}
The above expression evaluates to False, when it should clearly be True.
This works fine when fromList is used instead.
Tested on 6.8.2, but I don't see anything in the release notes vaguely
related for 6.8.3.
