Comment 1 Holger Hoffstätte 2023-08-05 13:48:40 UTC 
I can build libbsd-0.11.7-r2 just fine with glibc-2.38 using CFLAGS="-pipe -O2 -march=native -fno-semantic-interposition". This seems to be more of an LTO problem.
Comment 2 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2023-08-05 13:50:27 UTC 
It'll be the combination of the two with inclining I guess.
Comment 3 Ninpo 2023-08-05 14:44:03 UTC 
Definitely a combination, as it builds fine with LTO but without the -fno-semantic-interposition flag.
Comment 4 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2023-08-05 14:49:48 UTC

    It's needed for LTO at least.
