Could you file a pkg PR for this memtestplus so the package people are
aware of the issue going forward?  They might be able to do something
to mark broken platform or require that specific compiler, but at least
we can try some testing.  Could qemu or VirtualBox be used for testing
memtestplus, or only actual hardware?
