[Bug 1702204] Re: svn crashes when exporting a local checkout with root-relative svn externals

[Doug Brown]

The fix for this bug was released upstream in Subversion 1.9.9. It would
be great if the fix could be ported into 16.04 and 18.04.

Title:
  svn crashes when exporting a local checkout with root-relative svn
  externals

Status in subversion package in Ubuntu:
  New

Bug description:
  Ubuntu 16.04, subversion 1.9.3-2ubuntu1

  I have an SVN repository that has an svn:external that is relative to
  the root of the repository using the ^/ syntax. For example:

  ^/test.txt test2.txt

  With this type of external, I'm running into a bug: I can't use svn
  export if I specify a particular svn revision with the -r option to
  the svn command. For example, if I type this command:

  svn export -r 4 /home/doug/Downloads/myrepo-co/ myreportest4

  It prints out the following error, and then crashes:

  svn: /build/subversion-yttRtj/subversion-1.9.3/subversion/libsvn_subr/dirent_uri.c:322: canonicalize: Assertion `*src != '/'' failed.
  Aborted (core dumped)

  If I remove the -r 4 option, it doesn't crash and everything works
  perfectly.
