Global pointer variables misused in C programs

TL;DR: load global variables into local ones before use.

I've spotted a quite widespread misuse of global pointer variables. The issue is easily demonstrated by the following simplified example.

struct some_type_t {
    int a1;
    int a2;

dev-zzo

#include <stdio.h>
#include <malloc.h>
#include <math.h>
#include <stdlib.h>

//
// Generic N-layer neuron network code (using unipolar sigmoid activation function)
//

// Data type to operate on; typically double.
