If you're using Valgrind, you should call nng_fini() at the end of your tests otherwise you'll get spurious reports.

See the comments here:

nng/include/nng/nng.h

Lines 212 to 221 in e46b41a

 // nng_fini is used to terminate the library, freeing certain global resources. 

 // This should only be called during atexit() or just before dlclose(). 

 // THIS FUNCTION MUST NOT BE CALLED CONCURRENTLY WITH ANY OTHER FUNCTION 

 // IN THIS LIBRARY; IT IS NOT REENTRANT OR THREADSAFE. 

 // 

 // For most cases, this call is unnecessary, but it is provided to assist 

 // when debugging with memory checkers (e.g. valgrind). Calling this 

 // function prevents global library resources from being reported incorrectly 

 // as memory leaks. In those cases, we recommend doing this with atexit(). 

 NNG_DECL void nng_fini(void);

Thanks @shikokuchuo
After using nng_fini there is no memory leak report in valgrind.
