Result depends on evaluation order of a(z) and b(z)

[ettlmartin]

#include <iostream>
int a( int x)
{
	return x;
	//...
}
int b( int & y)
{
	// ...
	y++;
	return y;
	
}
int c( int z )
{
	return a(z) + b(z); 
}

int main()
{
}

The returned result from function c() depends of the calling order of a(z) and b(z). In other words, b(z)+a(z) computes another result as a(z)+b(z).

Mayba cppcheck could raise a warning in this cases, because these errors are hard to find.

Best regards
