Common libcurl mistakes

I'm planning a talk (video) on this topic and here I'm collecting the most common mistakes we've seen reported, discussed and revealed in recent years. What other mistakes do you see happen repeatedly?

1. Skipping the documentation!
2. Failure to check return codes
3. Forgetting the verbose option
4. There's a global init function
5. • that isn't thread-safe
6. Let users set (parts of) the URL
7. Consider the redirects
8. Unnecessary setting HTTP method
9. Disabled certificate checks
10. Assume zero terminated data in callbacks
11. C++ strings are not C strings
12. Threading mistakes
13. Understanding CURLOPT_NOSIGNAL
14. Forgetting -DCURL_STATICLIB

Forgetting a -DCURL_STATICLIB is pretty common (when using a static libcurl).
