Hey there,

I am using the libcurl version from Ubuntu 9.10 (7.19.5), so everything
I talk about may be fixed already.

I'm using the example from
http://curl.haxx.se/libcurl/c/getinmemory.html . Despite its calls to
curl_easy_cleanup() and curl_global_cleanup() it still leaks memory:

I don't know if this a bug imported from your linked libraries or if
it's your fault forgetting to tell them to free their resources.

Greetings,
