FX and Romain,
How many cores does each of your build systems have? Jeremy Sequoia says
he hasn't seen this on any of his build systems with APFS for MacPorts gcc6 or
later bootstraps but he is using 4 core systems in each case. I have seen
instances where particular race conditions don't show up on 8 core systems but
plague dual core systems.
