--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---
No, that's a VLA. When determining whether you have a VLA, this is the code the
compiler looks at:

  void func(const int n)                                                        
  {                                                                             
      std::vector<int> futs[n];                                                 

The way in which you call this function is not relevant; 'n' is not constant
here.
