Description Agostino Sarubbo gentoo-dev 2021-05-30 09:33:48 UTC

Issue: sys-libs/libstdc++-v3-3.3.6-r3 calls nm directly.
Discovered on: amd64 (internal ref: ci)

This machine uses GCC-11:
As per QA policy, toolchain tools must not be called directly because they can cause issue in cross-compiling and because is not possible use a different NM implementation (like llvm-nm). To reproduce, please use sys-devel/gcc-config[-native-symlinks], sys-devel/binutils-config[-native-symlinks].
