https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: sci-physics/pythia-6.4.28-r1 fails to compile with -fno-common. Discovered on: amd64 (internal ref: ci) NOTE: To reproduce this issue you may want to set CFLAGS="${CFLAGS} -fno-common" or compile it with gcc-10 that enables -fno-common by default.
