Code examples

The following code example fails the check and will give a warning:

volatile int v1;

extern void p ( int a[2] );

int x = 10;

void example(void) {
  int a[2] = { v1, 0 };
  p( (int[2]) { x++, x-- });
}

The following code example passes the check and will not give a warning about this issue:

void example(void) {
  int a[2] = { 1, 2 };
}
