You don't need a Windows build, valgrind on Unix shows that Arild's
analysis is correct. Using 'svn ci -N wc/foo' the problem occurs on
the *second* call to svn_path_condense_targets, with the code

                /* If a common prefix was found, condensed_targets
                   are given relative to that prefix. */
                if (basedir_len > 0)
                  rel_item += basedir_len + 1;
                
                (*((const char **)apr_array_push (*pcondensed_targets)))
                  = apr_pstrdup (pool, rel_item);

rel_item is an absolute path, something like "/home/pm/wc/foo", and
basedir_len is the strlen of that path. So adding basedir_len+1 to
rel_item produces a pointer to arbitrary memory.
