This happened the first some days ago. I then rebuilt libgcc, libgcc7, and gcc7 and can reproduce the failure. Installed are:

  gcc7 @7.5.0_4 (active) requested_variants='' platform='darwin 9' archs='ppc' date='2024-10-25T09:08:39+0200'
  libgcc @8.0_0 (active) requested_variants='' platform='any any' archs='ppc' date='2024-10-24T05:41:35+0200'
  libgcc7 @7.5.0_1 (active) requested_variants='' platform='darwin 9' archs='ppc' date='2024-10-24T05:37:58+0200'
