--- Comment #16 from Zdenek Sojka <zsojka at seznam dot cz> --- (In reply to Xi Ruoyao from comment #15) > patch: https://gcc.gnu.org/pipermail/gcc-patches/2021-November/584815.html Thank you for the patch; it fixes non-bootstrap build for me. I didn't check full bootstrap yet. Is there a chance to check why is there the strange behavior now, with the abort() in fixincludes? - parallel build hangs (eg. no "Error" or "Waiting for unfinished jobs" message from make) - non-parallel build succeeds (even though fixincludes aborted)
