Well I wasn't aware of that (though I'm running current rather than 1.6).
Where's the relevant PR?

How do you know it's the compiler? If it's a random behaviour, then my
first suspicion would be that it's some sort of timing issue (or cache
related). Compiler errors generally lead to repeatable problems. There
was a lot of hacking on the pmap in the run up to 1.6, and it wouldn't
surprise me in the least if that wasn't the cause of your problems.
