PPC64LE Fedora Rawhide LTO 3.10: https://buildbot.python.org/all/#/builders/674/builds/543 3 tests failed: test_cmath test_complex test_math That's a GCC 12 regression: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104389 |

@vstinner What was the change that caused the buildbots to start failing? Did the GCC version get updated on those machines between the last runs and this one, or was the change due to recent PRs in Python? |

> @vstinner What was the change that caused the buildbots to start failing? Did the GCC version get updated on those machines between the last runs and this one, or was the change due to recent PRs in Python? It's a GCC regression. GCC is updated frequently on the Rawhide buildbots. It's unrelated to Python. It's just that Python uses (Py_HUGE_VAL * 0.) for Py_NAN and this code is impacted by the bug. But I wrote https://github.com/python/cpython/pull/31134 since GCC 12 will no longer compute (Py_HUGE_VAL * 0.) during the compilation: it will be computed at runtime. See also https://bugzilla.redhat.com/show_bug.cgi?id=2050736 for details. -- The GCC regression is fixed in gcc-12.0.1-0.6.fc36 package. It will be deployed on buildbots shortly (and automatically). |

Rawhide buildbots are back to green: GCC has been fixed, I close the issue.
Moreover, Python 3.11 now uses NAN constant or __builtin_nan("").
