Sorry if I wasn't clear. I was trying to get the repo on my C: drive. Here's the same with more context: samg@PC0213 /cygdrive/c/temp/svn $ pwd /cygdrive/c/temp/svn samg@PC0213 /cygdrive/c/temp/svn $ svn co --username anonsvn https://smlnj-gforge.cs.uchicago.edu/svn/smlnj/admin test Authentication realm: Document repository Password for 'anonsvn': ******* assertion "svn_dirent_is_canonical(base, pool)" failed: file "/usr/src/packages/subversion/subversion-1.8.14-1.i686/src/subversion-1.8.14/subversion/libsvn_subr/dirent_uri.c", line 1053, function: svn_dirent_join_many Aborted (core dumped) But I also get the error with other svn commands that need the server (e.g. log). Command "svn status" does not give an error. The only kind of similar error messages I found on the web say something about not using a trailing slash with the URL.

Slightly edited because this is on my work pc and sysadmins don't like sharing much specifics. Not sure if they let me do much debugging there and I don't have any Windows at home. I appreciate any hints that might get this working again.
