The analyzer has detected an issue when an uninitialized variable is being passed into a function by reference or by pointer. The function tries to read a value from this variable.
Here is an example.
void Copy(int &x, int &y)
{
x = y;
}
void Foo()
{
int x, y;
x = 1;
Copy(x, y);
}This is a very simple artificial sample, of course, but it explains the point very well. The 'y' variable is uninitialized. A reference to this variable is passed into the Copy() function which tries to read from this uninitialized variable.
The fixed code may look like this:
void Copy(int &x, int &y)
{
x = y;
}
void Foo()
{
int x, y;
y = 1;
Copy(x, y);
}This diagnostic is classified as:
