Summary
Miscompilation allows memory corruption via CONVNOP-wrapped array copy in cmd/compile
Details

The compiler is meant to unwrap pointers which are the operands of a memory move; a no-op interface conversion prevented the compiler from making the correct determination about non-overlapping moves, potentially leading to memory corruption at runtime.
