        Why is this an issue?

        More Info

        <stdlib.h>'s abort, exit, getenv, and system have implementation-defined behaviors, and should therefore be avoided.

        Noncompliant code example

        #include <stdlib.h>
        
        void f( ) {
          exit(0); // Noncompliant
        }
