https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: dev-libs/pmdk-1.9.2 fails to compile with -fno-common. Discovered on: amd64 (internal ref: lto_tinderbox) NOTE: This machine uses lto with CFLAGS=-flto -Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing 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.

Fixed in 1.12.1, I assume.
