☠ Buildbot (Python): python/cpython - failed test (failure) (main)

The Buildbot has detected a new failure on builder x86 Debian Non-Debug with X 3.x while building python/cpython. Full details are available at: https://buildbot.python.org/#/builders/1245/builds/9638 Buildbot URL: https://buildbot.python.org/ Worker for this Build: ware-debian-x86 Build Reason: <unknown> Blamelist: Dmitry Voropaev <144015565+v0ropaev(a)users.noreply.github.com>, Stan Ulbrych <stan(a)python.org>, Victor Stinner <vstinner(a)python.org>, dependabot[bot] <49699333+dependabot[bot](a)users.noreply.github.com> BUILD FAILED: failed test (failure) Summary of the results of the build (if available): =================================================== == Captured traceback ================== Note: switching to '333071231d3a46cccc32d7f44b99328c3299d0b1'. You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by switching back to a branch. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -c with the switch command. Example: git switch -c <new-branch-name> Or undo this operation with: git switch - Turn off this advice by setting config variable advice.detachedHead to false HEAD is now at 333071231d3 gh-157649: Fix Py_CLEAR()/Py_SETREF() on C++ (#158070) Switched to and reset branch 'main' configure: WARNING: i686-pc-linux-gnu/gcc is not supported configure: WARNING: Platform "i686-pc-linux-gnu" with compiler "gcc" is not supported by the CPython core team, see https://peps.python.org/pep-0011/ for more information.
