This list is for development *of* Subversion, not development *with* Subversion.
  Many of the developers also subscribe to the users@ list, and would be equally
able to answer the question there. That being said...

Yes, you need to initialize your pools when using them with Subversion. The
book has a section on "embedding Subversion":
http://svnbook.red-bean.com/en/1.5/svn.developer.usingapi.html

And HACKING talks about pool usage conventions inside Subversion, but which may
also be useful in this context: http://subversion.tigris.org/hacking.html#apr-pools
