Hi,
I debugging crashes within the Trac (https://trac.edgewall.org/) when
using the svn backend. The issue seems to be related to Apache Portable
Runtime (APR) pool memory management at Trac together with subversion
SWIG python bindings and libsvn.
I am trying to run subverion with APR (lifetime) debugging enabled
(./configure --enable-pool-debug=all --enable-debug) to give more
insights, how-ever I got stuck with the basics.
First I tried 'svn' which completes fine:

=======================================================================================================================================================
I tried subversion 1.14.1 and subversion-trunk@1889032. Traces above are
generated using the subversion-trunk codebase.
I have also the unittests of the Apache Portable Runtime (APR) on which
the relevant(?) ones completes successfully.
How can I find out if a) I am looking at an potential issue within
subversion source code, b) whether the APR debugging is flagging this as
a false positive or c) something else?
Kind regards,
Rick
