I made sure that this is not due to _FORTIFY_SOURCE=3 by replacing all __bdos calls with __bos.  It is reproducible by attempting to build the preprocessed source with:

gcc/cc1plus -quiet /tmp/ceph.ii -std=c++20 -fno-strict-aliasing -o /dev/null

on gcc trunk as of Feb 6th.  Most likely a c++ issue.

Yes, it was bisected to a C++ FE change.
Comment 4 Kaleb KEITHLEY 2023-03-13 18:08:14 UTC 
Can confirm that the fix included in gcc-13.0.1-07 works and I have now successfully built ceph in koji.
