clang-stricter_tinderbox has reproduced this issue with version 6.00 - Updating summary.
Workaround is to use gcc instead of clang? Probably should add in title that this is a clang build of memtest86+ issue? I happened to chance upon this bug on one of my machines that somehow has 'cc' pointing to clang by default. Changing to gcc worked around the problem.
Can anyone test if this still affects 6.10 and/or 6.20?
