@seankhliao does this only happen on FreeBSD 12.2 and not prior FreeBSD versions? If so, maybe #43873 is related as well.

[seankhliao]

No idea, I don't run freebsd

[problame]

@seankhliao sorry, that was meant to be an @bakul

[bakul]

No ideas as I don't have any machine running any older versions of FreeBSD.

This problem seems to have disappeared with go1.16 and FreeBSD-13.0-* -- closing this for now at least.
