Description

see http://shaman.ceph.com/builds/ceph/nautilus/

nautilus was building fine on openSUSE Leap 15.1 up to a3114e97c92742b791205cde9b104718f1459a56

then something got merged which broke the Leap 15.1 build. The failure is:

[ 6987s] I: Program returns random data in a function
[ 6987s] E: ceph no-return-in-nonvoid-function /home/abuild/rpmbuild/BUILD/ceph-14.2.4-457-g2df6575/src/rgw/rgw_rest_s3.cc:3383

(This issue is not limited to openSUSE Leap 15.1, but that OS is the only one that does static analysis as part of the build process.)

This first showed up in Shaman for 2df6575e9d449637265f9d7b19ce159636814a1e - so, with a high degree of certitude we can say that the culprit is likely to be one of the following PRs:

Here is the "serious compiler warning" that is failing the openSUSE build:
