Are you running your local tests using the same configuration the
builder uses? (Even without looking up the build script, the builder's
name suggests it uses FSFS f6, i.e., --server-minor-version.)

If you haven't already, re-run that builder using subversion-bot to
check if the bug is reproducible.

The error trace goes through cache.c; SVN_X_DOES_NOT_MARK_THE_SPOT in
notes/knobs can be used to rule out svn_cache__t as the cause.
