Its standard behavior.

Posix: https://pubs.opengroup.org/onlinepubs/009695399/functions/free.html "If ptr is a null pointer, no action shall occur. "
Windows: https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/free?view=msvc-160 " If memblock is NULL, the pointer is ignored and free immediately returns. "

So it should be okay.
