Potential security issue in src_c/_sprite.c: Unchecked return from initialization function

[monocle-ai]

What is a Conditionally Uninitialized Variable? The return value of a function that is potentially used to initialize a local variable is not checked. Therefore, reading the local variable may result in undefined behavior.

2 instances of this defect were found in the following locations:

Instance 1
File : src_c/_sprite.c
Function: __Pyx_CallUnboundCMethod1
https://github.com/siva-msft/pygame/blob/0f3cde6bc1377f9ecb1365c78900c3ef852f926a/src_c/_sprite.c#L29339
Code extract:

#endif
    else {
        if (default_value == Py_None)
            value = __Pyx_CallUnboundCMethod1(&__pyx_umethod_PyDict_Type_get, d, key); <------ HERE
        else
            value = __Pyx_CallUnboundCMethod2(&__pyx_umethod_PyDict_Type_get, d, key, default_value);

How can I fix it?
