Postgres resources not released after call PQclear

Hello;
I observe that when the row number about a SELECT SQL request is equal to zero, the function PQclear does not release the allocated resources and a memory leak are detected into my application.
To reproduce the problem I do the following steps:

- To detect the memory leak I have enabled them via the Microsoft procedure .

Include the following files

#define _CRTDBG_MAP_ALLOC

#include <stdlib.h>

#include <crtdbg.h>

And I call the function _CrtDumpMemoryLeaks() at the end of my application, to display all the memory leak.

- I call the PQexec function to execute the SQL request and after it end I call PQclear to release the allocated ressouces.

Can you give me a help about this bug?
Best regards;
