String buffers are not freed when pointers to them (created via ctypes.cast) are deleted, even though those pointers hold references to the string buffer (in tagCDataObject.b_objects, I think). Code examples can be found on StackOverflow.com [1]. Thanks to Mark Tolonen's answer on that StackOverflow post we know that it is a refcount problem.

Tested in
  Python v3.7.4 x64 on Windows 10 x64, and in
  Python v3.8.2 x64 on ArchLinux x64 (5.6.7-arch1-1)
