I'm able to reproduce the assertion with pre-8078629 binaries, so the problem existed before. The code which triggers the assertion: static void testUnsafeGetAddress() { long cookie = 0x12345678L; U.putAddress(nativeAddr, cookie); for (int i = 0; i < 20_000; i++) { Asserts.assertEquals(checkGetAddress(), cookie); } } @DontInline static long checkGetAddress() { return U.getAddress(nativeAddr); } Problematic StoreP corresponds to U.putAddress(nativeAddr, cookie)
