I am also using `0.3.6.3`, but I cannot reproduce it. ``` Prelude System.FilePath.GlobPattern> "foo/bar" ~~ "*/*" True Prelude System.FilePath.GlobPattern> "Hpack/Config.hs" ~~ "*/*.hs" True ```

@nh2 I figured out why I could not reproduce it. I am on Windows. The Windows `pathSeparator` is not '/'. `matchDir (c:_) | c == pathSeparator = fail "path separator"`...

You should escape `\` in glob patterns. ``` > "a\\b" ~~ "a\\\\*" True ```
