Potential security issue in src_c/math.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.

1 instance of this defect were found in the following locations:

Instance 1
File : src_c/math.c
Function: _scalar_product

pygame/src_c/math.c

Line 1335 in 24dc49f

tmp = (_scalar_product(self->coords, other_coords, self->dim) /

Code extract:

        PyErr_SetString(PyExc_ValueError, "can't use slerp with Zero-Vector");
        return NULL;
    }
    tmp = (_scalar_product(self->coords, other_coords, self->dim) / <------ HERE
           (length1 * length2));
    /* make sure tmp is in the range [-1:1] so acos won't return NaN */

How can I fix it?
