The API contract in partition_version.hh states that when dealing with
evictable entries, a real cache tracker pointer has to be passed to all
methods that ask for it. The nonpopulating reader violates this, passing
a nullptr to the snapshot. This was observed to cause a crash when a
concurrent cache read accessed the snapshot with the null tracker.
A reproducer is included which fails before and passes after the fix.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
