Resolution Note (fix version 2021.1):
Fixed issue where thread statics that reused thread static slots would not adhere to type alignment. This would cause the garbage collector to incorrectly clean up thread static data because it would only scan pointer aligned memory for references. This would lead to memory becoming corrupted and inducing random crashes.
