<p>The rule finds code that initializes a global variable (i.e. uses it as an L-value) but is never called from <code>main</code>.
|
|
Unless there is another entry point that triggers the initialization, the code should be modified so that the variable is initialized.
|
|
Uninitialized variables may contain any value, as not all compilers generate code that zero-out memory, especially when
|
|
optimizations are enabled or the compiler is not compliant with the latest language standards.
