I have a little re-run information now:
No -JN with ALLOW_MAKE_JOBS=3Dyes: seems repeatable
-J1 with ALLOW_MAKE_JOBS=3Dyes: seems repeatable
-J1 without ALLOW_MAKE_JOBS: mixed so far in the one run.
For -J1 without ALLOW_MAKE_JOBS for as far as the bulk
build has gotten (still in progress):
[00:22:03] [01] [00:21:12] Finished devel/cmake | cmake-3.19.6: Failed: =
configure
[00:23:04] [01] [00:00:59] Finished textproc/libxslt | libxslt-1.1.34_1: =
Success
[00:33:35] [01] [00:00:19] Finished textproc/itstool | itstool-2.0.6: =
Failed: configure
Some ports dependent on libxslt-1.1.34_1 are building as well,
devel/glib20 , textproc/minixmlto , and x11/xkeyboard-config
have built.
I'm not sure it is reasonable to wait on -J1 without
ALLOW_MAKE_JOBS to see what the devel/gdb and
x11-toolkits/libXaw build does. For example qt5-core
that is now building and may not be worth waiting for.
The results do suggest that the issue is racy, no matter
if the number of active processes/threads changes the
probabilities involved or not.
