segfaults on AIX 5.1L

I've been trying to get subversion 1.0.2 built and running on AIX 5.1L. Without
expat or libxml it builds out of the box but segfaults during most svn
operations (mostly co) (see stack dump below).

I installed expat-1.95.2 (in the default place - /usr/local) but the configure
did not seem to like the expat.h file. Then I installed libxml-2.6.3,
reconfigured and built subversion and this version works fine. I don't know
exactly why subversion segfaults but perhaps this will help others hitting
the same problem. If anyone working on subversion wants to investigate the
segfault with the subversion included expat I am happy to help out.

bash-2.04$ dbx /usr/local/bin/svn core
