Michael,
Thanks for tracking down where the additional failures began. I took a quick
look at the buildbot listings for builds 325 and 325 and it seems like all of
the additional failures that appear in 326 vs 325 are a result of a new build
failure for the pyexpat module. That's visible at the end of the "compile"
stage output:
Failed to build these modules:
pyexpat
and near the top of the test output when the Makefile tries to rebuild any
failed modules.
Looking at the output of the git stage of 326, the git branch HEAD of the build
is 9d4712bc8f26bf1d7e626b53ab092fe030bcd68d. Running git show to get the
commit message:
$ git show 9d4712bc8f26bf1d7e626b53ab092fe030bcd68d

bpo-35011: Restore use of pyexpatns.h in libexpat (GH-9939)
Restores the use of pyexpatns.h to isolate our embedded copy of the expat C
library so that its symbols do not conflict at link or dynamic loading time
with an embedding application or other extension modules with their own
version of libexpat.
https://github.com/python/cpython/commit/5dc3f23b5fb0b510926012cb3732dae63cddea60#diff-3afaf7274c90ce1b7405f75ad825f545
inadvertently removed it when upgrading expat.
That looks rather suspicious!
So I guess the next step would be to try to figure out why that change (or some
other in the range between buildbot run 325 and 326) causes the pyexpact module
to stop building. There are a bunch of ld: 0711-317 ERROR: Undefined symbol
errors in the link step of the "building 'pyexpat' extension" step. In the
"configure" step, it is determined that it is not using an operating system
provided version of expat:
checking for --with-system-expat... no
Which is to be expected. So it should be trying to pick up a version of expat
that is provided elsewhere outside of the build. Perhaps there is an issue
with it. Or the above change doesn't take something into account. To proceed
further, it would be most helpful to have someone with AIX experience and/or
familiarity with that buildbot's setup.
