Comment 6 for bug 1451028

[Impact]

Subversion's Perl bindings randomly crash. This is most typically seen when using git-svn, since it's a heavy user of the bindings.

[Test case]

"git svn clone -s svn://svn.code.sf.net/p/flightgear/fgaddon". With the existing package in xenial, git-svn kept crashing while trying to checkout the first revision. With the updated package, I've successfully processed 2400 revisions before being interrupted by a network issue.

[Regression potential]

This brings the code up to date with current released Subversion code in this area. The upstream release which included these changes (1.9.5) has been in Debian since 2016-11-29 and I've received no further reports of issues.
