Trying to help someone on SO, I ran into problems.

On a 64-bit Linux machine, with DMD 2.055

This gives:  '/Internal error: ../ztc/cg87.c 202'
void main(){

  auto f = (double m){ static double sum = 0.0; return sum += m * m; };
  double[] a = array(map!f(iota(1.0, 25.0, 1.0)));
  writeln(a);
}


This one compiles but I get Segmentation fault.
void main(){

   auto f = (double m){ /* static double sum = 0.0;*/ return m * m; };
   double[] a = array(map!f(iota(1.0, 25.0, 1.0)));
   writeln(a);
 }


This one compiles and runs.
 void main(){

   auto f = (double m){ /* static double sum = 0.0;*/ return m * m; };
   double[] a = array(map!f(array(iota(1.0, 25.0, 1.0))));
   writeln(a);
   //works
 }


Putting everything together, I still get 'Internal error: ../ztc/cg87.c 202'
with this one.
void main(){

  auto f = (double m){ static double sum = 0.0; return sum += m * m; };
  double[] a = array(map!f(array(iota(1.0, 25.0, 1.0))));
  writeln(a);
}
