Summary

futures_task::noop_waker_ref can segfault due to dereferencing a NULL pointer

Details

Affected versions of the crate used a UnsafeCell in thread-local storage to return a noop waker reference, assuming that the reference would never be returned from another thread.

This resulted in a segmentation fault crash if Waker::wakebyref() was called on a waker returned from another thread due to it attempting to dereference a pointer that wasn't accessible from the main thread.
