You're probably right, for the simple test case you present, but there have
been by my count five memory leaks fixed in curl since 7.17.1.

Are you using OpenSSL? Which version? A Win32 leak was just fixed there
earlier today. Please try using the latest nightly build and see if
you can still reproduce the leak. How are you determing that there is
a leak, anyway?
