Unfortunately, backporting your patch is not enough; it depends on another, and
backporting the dependency generates many conflicts.

There is now a ./install-dependencies.sh in the scylla repositories, so to get
a reproducer, you can (on Fedora)

    git clone  --recurse-submodules https://github.com/scylladb/scylla
    sudo ./install-dependencies.sh  # just running yum, honest
    ./configure.py
    ninja build/debug/tests/view_schema_test_g   # add -j smallnum if running
out  of memory
    build/debug/tests/view_schema_test_g -- --smp 1 -m1G   # will reproduce the
problem
