change entry to use unsafe.Pointer instead of atomic.Pointer[V] - #2
Merged
Conversation
The expunged sentinel is 16 bytes, allocated as new(any). If V is larger than that, casting expunged to *V triggers checkptr violations since extra memory is referenced. Using unsafe.Pointer lets us just compare pointer values without the casting.
