--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> --- Reported to the GMP mailinglist, not sure which libaries fault it is. To complete library version list, GCC reports GNU C17 (SUSE Linux) version 8.2.1 20180831 [gcc-8-branch revision 264010] (x86_64-suse-linux) compiled by GNU C version 8.2.1 20180831 [gcc-8-branch revision 264010], GMP version 5.1.3, MPFR version 3.1.2, MPC version 1.0.2, isl version none but I'll try what we recommend as prerequesites now.
