malformed argument re-use in svn_client_url_from_path2

Hi,
  the function "svn_client_url_from_path2" in "libsvn_client/url.c" re-uses the const char* argument "path_or_url" as both output and input of the svn_dirent_get_absolute call and this causes the function to crash. The crashing line is:

  SVN_ERR(svn_dirent_get_absolute(&path_or_url, path_or_url, scratch_pool));

  The description of my developing environment is:

  O.S.: Windows 7
  Release: Subversion 1.8.3
  Compiler: MS Visual Studio 2010
  No modifications to SVN
  DB: FSFS
 Additional details: I replicate the problem using the same const char * variable in both arguments of the svn_dirent_get_absolute call (crashing in the same way) and made it to pass ok on this call by having another const char * as output. Replicated code snipet crashing:

  err = svn_dirent_get_absolute(&path, path, local_pool);

  And the ok code snipet:

  const char *local_path=NULL;
  err = svn_dirent_get_absolute(&local_path, path, local_pool);

  Should the function "svn_client_url_from_path2" have a "local_path_or_url" variable for output as all the other client functions that use "svn_dirent_get_absolute" have?

Thanks for your attention,
