Check these tests:
```
void test_fuse_nested_reverse(void) {
  int i, j, k, l;
  #pragma omp fuse
  {
    #pragma omp fuse looprange(1, 2)
    {
      for (i = 0; i < 10; i++) ;
      for (j = 0; j < 15; j++) ;
      #pragma omp reverse
      for (k = 0; k < 5; k++) ;
    }
    for (l = 0; l < 4; l++) ;
  }
}
void test_fuse_reverse_captured_bound(int n) {
  int i, j;
  #pragma omp fuse
  {
    for (i = 0; i < 10; i++) ;
    #pragma omp reverse
    for (j = 0; j < n + 1; j++) ;
  }
}
```
