What curl version? Curl had in the past some memory leaks.
Test with a current version if you have used an old version.

Are you sure that the memory is freed after libcurl cleanup
and not by program end? Maybe the leak is in your code.

Use a tool like valgrind to hunt for memory leaks.

And without your code it's hard to to help you.
Can you send us at least your write callback?
