arrays without compile-time bounds aren't shown at all

[pgbovine]

x doesn't show up here since its bounds don't seem to be picked up at compile-time ...

const int DIM1 = 3;
const int DIM2 = 4;

void fint(int param[DIM1][DIM2]) {
  return;
}

int main() {
  int x[DIM1][DIM2];
  int i, j;
  for (i = 0; i < DIM1; i++)
    for(j = 0; j < DIM2; j++)
      x[i][j] = i+j*i;
  fint(x);
  return 0;
}

I think in general, arrays without compile-time bounds aren't rendered; not just multi-dimensional

int main() {
  int x = 42;
  int arr[x];
  return 0;
}

another example of a variable-length array

int foo() {
  int x = 13;
  int y[x]; // <-- not shown in visualizer
  y[0] = 42; // <-- not shown in visualizer
  return 0;
}

int main() {
  foo();
  foo();
}
