Versions from 0.2.2 and before 0.3.6 of crate 'futures' did not properly implement a 'static lifetime bound on the waker function. This resulted in a use-after-free if Waker::wake() is called after original data had been dropped. The flaw was corrected by adding 'static lifetime bound to the data waker takes.
