The following should either be compile correctly or rejected as not supported:
```console
$ cat seen.c
#include <stdio.h>

int seen[6] = {0};
int main() {
  #pragma omp tile sizes(3, 5)
  #pragma omp tile sizes(2)
  for (int i = 0; i < 6; ++i)
    ++seen[i];

  for (int i = 0; i < 6; ++i)
    printf("seen[%d]=%d\n", i, seen[i]);;

  return 0 ;
}                                                                                                                                                                                                  $ bin/clang seen.c -O3 -fopenmp -o seen && ./seen
seen[0]=3
seen[1]=3
seen[2]=0
seen[3]=0
seen[4]=0
seen[5]=0                           
```
