--- Comment #7 from Vittorio Zecca <zeccav at gmail dot com> ---
With gcc 6.1.0, maybe a shorter reproducer
/* gcc -fcheck-pointer-bounds -mmpx p.c */
int main ()
{
  int size = 10;
  typedef struct
    {
      char val[size];
    } block;
  block b;
  block retframe_block () {}
  retframe_block ();
}
