Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2017-08-13 Ever confirmed|0 |1 --- 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.
