I'm guessing you see a combination of a few bugs. The internal canonical format of URLs requires that you use the file://D:/none/existing form and no backslashes. The argument parser should probably convert this for you or produce a proper error.
After that all the internal code requires the internal format and you found various error paths, but all of them have the same root cause: an invalid URL going through to the lower layers.

It crashes when the target repo cannot be found and the current folder is a repo. This bug can be reproduced with the following commands: mkdir my-repo svnadmin create my-repo cd my-repo svnsync sync file:///D:\non\existent\folder svnsync sync file:///D:\folder\without\a\repo Here is the error message before it crashes: svn: E235000: In file 'D:\Development\SVN\Releases\TortoiseSVN-1.8.8\ext\subvers ion\subversion\libsvn_ra_local\split_url.c' line 78: assertion failed ((*fs_path )[0] == '/') My testing configuration: Windows 7 SP1, 64 bit TortoiseSVN 1.8.8, Build 25755 - 64 Bit , 2014/08/10 14:44:06 Subversion 1.8.10, -release apr 1.5.1 apr-util 1.5.3 serf 1.3.7 OpenSSL 1.0.1i 6 Aug 2014 zlib 1.2.8 Hope this helps, Dung.
