Changelog
+Daniel Stenberg (7 Jul 2008)
+- Scott Barrett provided a test case for a segfault in the FTP code and the
+ fix for it. It occured when you did a FTP transfer using
+ CURLFTPMETHOD_SINGLECWD and then did another one on the same easy handle but
+ switched to CURLFTPMETHOD_NOCWD. Due to the "dir depth" variable not being
+ cleared properly. Scott's test case is now known as test 539 and it
+ verifies the fix.

response codes. Previously libcurl would hang on such occurances. I added
