I typed the following before realizing that this commit was ultimately reverted, but figured I'd provide the insight for others' sake anyway. Bert, you can ignore this. :-)
{{{
Actually, I don't think this is a longstanding bug at all. The
svn_ra_get_uuid() and svn_ra_get_repos_root() interfaces promise to return
these values allocated *in the session pool*. As such, the ra_local
implementations thereof purposely do *not* dup into the passed-in POOL.
It's the svn_ra_get_uuid2() and svn_ra_get_repos_root2() wrapper functions
which do that duplication. Bert's commit needs to be reverted, and the
appropriate pool lifetime fix made elsewhere.
