I switched from gcc 4.9.4 to 5.4.0. After that dev-db/mysql-workbench-6.3.4-r1 fails to build. Solution for me: use dev-db/mysql-workbench-6.3.4-r2 At time of writing this version is not yet stable. Solution would be to have this one stable. Reproducible: Always Steps to Reproduce: 1. Use gcc-5.4.0 2. emerge -1av dev-db/mysql-workbench (version 6.3.4-r1) Actual Results: Fails to build. Expected Results: Build should work.

Can't attach my build log....
You need to compress the log first. xz -9 /var/tmp/portage/<category>/<packagename>/temp/build.log https://wiki.gentoo.org/wiki/Bugzilla/Bug_report_guide#Problems_at_build_time Review your gcc upgrade. A gcc upgrade is not trivial and source of many problems. Please try check it together with out wiki and our support channels and provide more information as soon as possible and reopen the ticket. https://www.gentoo.org/support/
