It's hard to check whether old opcache bug reports have been resolved, because these issues tend to be non-reproducible. It's quite likely that they are, as opcache is tested much more extensively now than it was a few years ago. Back then, the file cache had essentially no automated tests, while nowadays we check our test suite with all four file cache combinations (written with/without SHM, read with/without SHM). Restarts are an area that still doesn't have much in terms of automated tests, but at least it's covered by fuzz testing.
