I gave up trying to follow the auth stuff. However, at around line
720 svn_ra_dav__open calls svn_auth_set_parameter and passes things
allocated from its pool and these get stored in the hash passed via
the callbacks argument, so it looks like the hash could well have a
longer lifetime than the dav session. Perhaps a pool cleanup function
should clear the auth parameters? I wonder if there are other cases
where svn_auth_set_parameter does something similar?

Interesting, what do you see as the advantage of --enable-dso?
