--- Comment #5 from Mark Millard <marklmi26-fbsd@yahoo.com> ---
I tried a build targeting armv7 and it completed okay.

I replicated the failure for targeting aarch64, using
bulk -w -i . But the -i only shows the following in
/tmp :

# ls -Tldt /tmp/*
-rw-r--r--  1 root  wheel  0 Jun 25 10:08:38 2022 /tmp/su-to-portbuild
drwxr-xr-x  2 root  wheel  7 Jun 25 10:08:03 2022 /tmp/packages

Looking: it executes in /usr/local/poudriere/data/.m/main-CA72-default/ref/
and no numbered main-CA72-default/*/ exist at the time. So the relevant
tmp/ has been cleaned out already.

I was able to expand the -w created archive and re-execute the failing
command and get the (or a) failure. I'll see about trying to get a
.txz of the .cpp and .sh from tmp/ as an attachment. (No web
browser or GUI for the aarch64 machine involved. So things are less
direct. I'm not aware of a way to directly add the attachment to
this bugzilla entry from such a context.)

Note: My buildworld has clang built without assertions but it still
fails. Thus the assertion failure would be unlikely to be a false
positive.
