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.
