delete_array aborts the program

[Nenad Vukicevic]

I have a simple program that sigaborts on delete_array().

#include <upcxx/upcxx.hpp>
using namespace upcxx;

#define DSIZE 128
global_ptr<int> my_data;

int main () {
  int ldata[DSIZE];

  upcxx::init();
  my_data = new_array<int>(DSIZE);
  {
    future<> f = rput (ldata, my_data, sizeof(ldata));
    while (!f.ready())
      progress();
  }
  barrier ();
  delete_array (my_data);
  finalize();
}

(gdb) where

This program has a buffer overrun - the rput argument should be sizeof(ldata)/sizeof(int).

See if that fixes the crash.

Yes. I keep forgetting the typed interface.
