Yeah. I saw it on numerous architectures, x86 and x86_64.
I believe I saw it on aarch64 and ppc as well, but I don't
have build logs at hand to confirm.
I'm running the tests with and without your patch as well.
So far I've run t9128 300 times with the patch and no
failures. Without it, it's failed 3 times in only a few
dozen runs. That's promising.
Thanks for poking this Eric, and Brian for bringing it up.
I had intended to look at it again and mention it,
eventually. :)
