--- Comment #4 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
We have a Homebrew user report it, and I can see it myself. It is intermittent,
and I have seen it happen twice, always with "make -j4" (2 out of 4 parallel
builds). Building with -j1 does not appear to trigger the issue.
