Arm64 stack issues (was Re: FreeBSD status for/on ODroid-C2?)

Sat Jan 28 22:18:09 UTC 2017

Note that on the pine64 the network interface hangs from time to time and I
get a core dump with very low frequency from long running processes, eg the
shell that invokes "make world". Note that I had similar issues on the
ODroid-C2.

Currently rebuilding world without MALLOC_PRODUCTION.

The arm64 port is getting close to working 100%, just a last few glitches.
