Thank you for taking the time to submit an issue!
Background information
What version of Open MPI are you using? (e.g., v4.1.6, v5.0.1, git branch name and hash, etc.)
5.0.7
Describe how Open MPI was installed (e.g., from a source/distribution tarball, from a git clone, from an operating system distribution package, etc.)
Building from source tarball (https://download.open-mpi.org/release/open-mpi/v5.0/openmpi-5.0.7.tar.bz2)
If you are building/installing from a git clone, please copy-n-paste the output from git submodule status.

Then the build (make -j 8) fails with:

If I reverse the change to oshmem/mca/sshmem/base/sshmem_base_open.c from #12889 then I do not see the failure. So a patch of:

Should this be? Or something else?
