I build my arm versions with threads by default and I didn't notice this one. I can obviously reproduce it as well. The problem doesn't happen on x86_64 because it has the macro HA_CAS_IS_8B defined and it can fall back to the regular CAS macro which is implemented in this case. We should have a higher level HA_CAS_DW function that supports absence of threads and use this one instead. I'll double-check with Olivier. Thanks, Willy
