--- Comment #40 from Campbell <rlcamp.pdx at gmail dot com> --- (In reply to Chris Johns from comment #38) > FYI I do not see any build errors with the same version of MacOS on > different hardware running HPFS. It is a different machine with a Fusion > disk and that disk is not supported by APFS. Yes, the problem is known to be specific to APFS, due to the finer resolution of timestamps. Why is .NOTPARALLEL not an acceptable solution, until a more thorough solution is found? Is it actually possible to have an even reliably measurably longer build time due to .NOTPARALLEL? It fixes the problem, albeit in an overly conservative way. It would be much worse for it to continue to not work at all.
