New comment by Duncaen on void-packages repository https://github.com/void-linux/void-packages/pull/35077#issuecomment-1026332415 Comment: libstdc++ uses it when tbb is installed or used, thats why the toolchain needs to be updated, easyeffects is fine. Edit: easyeffects just uses std::execution, which breaks with the tbb update and is fixed in gcc-11+. https://github.com/wwmm/easyeffects/commit/dfa0e853e0480eb9937747302b86e0dedc58054e
