Thanks. That allowed me to reproduce the issue locally. I tracked down it was due to the emulation of a POWER9 CPU, things work fine with a POWER8 CPU. I found that it has been fixed recently in the upstream 2.33 branch: https://sourceware.org/git/?p=glibc.git;a=commit;h=c493f6a0e4dcd6fff22da0df9fb2e52ecf4ffff1 -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://www.aurel32.net
