Tom Lane reported another instance today:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=tadarida&dt=2021-11-11%2013%3A29%3A58
Each of the three failures happened on a sparc64 Debian+gcc machine. I had
tried ~8000 iterations on thorntail, another sparc64 Debian+gcc animal,
without reproducing this.
