I encountered the problem when I tried to emerge sys-devel/gcc-10.2.0-r5 on my Raspberry Pi 4. It's a rather fresh 32bit installation. It was discussed here: https://forums.gentoo.org/viewtopic-t-1131744.html As a test I set '-icu' in make.conf and rebuilt world ('emerge -auvDNU world') and gcc emerged successfully. Reproducible: Always Steps to Reproduce: 1. emerge -1av sys-devel/gcc 2. 3. Actual Results: (...) msgfmt -o de.mo /var/tmp/portage/sys-devel/gcc-10.2.0-r5/work/gcc-10.2.0/libstdc++-v3/po/de.po msgfmt -o fr.mo /var/tmp/portage/sys-devel/gcc-10.2.0-r5/work/gcc-10.2.0/libstdc++-v3/po/fr.po msgfmt: symbol lookup error: /usr/lib/libicuuc.so.68: undefined symbol: _ZSt14__once_functor, version GLIBCXX_3.4.11 make[5]: *** [Makefile:551: de.mo] Error 127 make[5]: *** Waiting for unfinished jobs.... msgfmt: symbol lookup error: /usr/lib/libicuuc.so.68: undefined symbol: _ZSt14__once_functor, version GLIBCXX_3.4.11 make[5]: *** [Makefile:551: fr.mo] Error 127 (...) Expected Results: That sys-devel/gcc is emerged successfully. It seems that all packages which make use of 'libicuuc.so.68' while emerging are affected.

Yeah, ideally gcc should stop injecting with LD_PRELOAD it's locally built libstdc++.so. It also breaks linkers occasionally. As a workaround we could try disabling doc building (again).
Let's reverse mark as dupe as the other has.. more dupes and discussion. *** This bug has been marked as a duplicate of bug 843119 ***
