Memory leak libcanrad

When using the module, we periodically observe that the canardFree is trying to release the null pointer.
canardAlloc: 30688416 bytes: 40
canardFree: 30688416
canardAlloc: 31360032 bytes: 32
canardAlloc: 30720600 bytes: 12
canardFree nullptr

Can you tell me how to solve this problem? We use version 1.1

This is not a problem. Freeing a null pointer is a no-op, and it is well-specified.
