Re: Troubles building world on stable/13

avoid mixing the issues.]

I do not see anything between your:

Thank you, the script reports:
branch: stable/13
merge-base: d7b156672a48c37e1b8ce9b4ae28a46ecea55412
merge-base: CommitDate: 2022-01-21 15:58:11 +0000
d7b156672a4 (HEAD -> stable/13, freebsd/stable/13) zone.9: Remove documentation of non-existent NUMA configuration flags
n249092 (--first-parent --count for merge-base)

and where I'm at for stable/13:

branch: stable/13
merge-base: a5f69859956049b5153b0e1b67f8f4a99622dc6f
merge-base: CommitDate: 2022-01-15 12:55:32 +0000
a5f698599560 (HEAD -> stable/13, freebsd/stable/13) Ignore debugger-injected signals left after detaching
n249004 (--first-parent --count for merge-base)

that would seem a likely explanation for why I
did not see the problem when I built.

The same goes for between your stable/13-n248948-9418a626103
starting point and where my stable/13 environment is at.

(In my case, I also build for poudriere and chroot trees,
not just booting. So multiple builds are involved in the
sequence.)

I've not come up with any ideas beyond the 2:

A) Trying the two files that failure produced for attempted
reproduction of the problem (such as):

/tmp/gmock-all-836ef8.cpp
/tmp/gmock-all-836ef8.sh

but in other system-clang 13 contexts to see if the problem is
reproducible off that RPi3*.

B) Doing the /usr/obj/. . . cleanout and then a build-from-scratch
attempt.
