--- Comment #19 from Kazumoto Kojima <kkojima at gcc dot gnu.org> --- (In reply to John Paul Adrian Glaubitz from comment #18) > You seem to be on to something here as, in fact, mpfr had problems > previously when built with "make check" [1]: I see many segfaults and bus errors in [1]. Clearly this mpfr is problematic to use in compiler. It might show some other problem of the compiler which was used to build mpfr, though I have no experience for such failures. Anyway your current mpfr looks broken and should be replaced with the sane one. > Assuming that mpfr would be the origin of this, would this also explain the > segmentation faults in the recently compiled systemd package? Because > apparently the systemd binaries crash because gcc has produced broken code > here. Could it be possible that the compiler made some float calculation > which gave a weird result, embedded that into systemd which in turns > segfaults? There is too little information to say something and there are many possibilities, I think.
