I've publicly reported at least one issue: https://lists.freebsd.org/pipermail/freebsd-current/2017-July/066468.html It also seems that setting stack_guard_page to any positive integer value greater than 1 causes issues. For example, lang/rust will fail to build and some GUI applications will fail to start. I've also noticed a regression with mysql56-server when stack_guard_page is set to a positive integer value greater than 1. All my testing so far has only been on amd64. I have arm64 devices running the same code, but they don't do nearly as intensive work as my amd64 systems. It seems the MAP_GUARD work needs more exhaustive testing on 12-CURRENT.
