I built 6.2.1 on macOS 10.13.6 (18-core Xeon W, iMac Pro). The build
was successful. I changed to the “tune” directory, and ran “make
tuneup”, and then ran “tuneup” (no arguments).
Then I got an alert indicating that “tuneup” had crashed. The crash
log from the alert is attached. The output from the build did not
indicate (to me, at least) a problem. That output is also attached.
Sometimes the tuneup program gives up because it cannot reliably measure
executon times. The reason can be that the system is loaded, or that
the system kernel provides poor clock and/or cycle counting support.
