Description
Affected versions of this crate implemented Sync
for LateStatic
with T: Send
, so that it is possible to create a data race to a type T: Send + !Sync
(e.g. Cell<T>
).
This can result in a memory corruption or other kinds of undefined behavior.
The flaw was corrected in commit 11f396c by replacing the T: Send
bound to T: Sync
bound in the Sync
impl for LateStatic<T>
.
