Appropriate -subslots in mpfr and slot-operators in dependencies in mpc and gcc will -cause a rebuild of mpc and gcc after an upgrade of mpfr. - -However, after mpfr-4 is installed and mpc rebuiltd, but *before* gcc is -rebuilt, gcc will be in an inconsistent state wherein symbols from -incorrect library versions of mpfr might get used. This can result in -segfaults and internal compiler errors. It is therefore important to -rebuild gcc immmediately after mpc. - -A detailed update guide with troubleshoot section can be found on the wiki: -https://wiki.gentoo.org/wiki/Mpfr4-update-guide |
