I'll post the bug.

Just to help narrow the problem down, this works:

import std.stdio;

struct SPoint
{
   double x,y;
   static SPoint create(double x,double y)
   {
     SPoint p;
     p.x = x;
     p.y = y;
     return p;
   }
}

void main()
{
   SPoint[] sps;
   sps ~= SPoint.create(1,2);

//sps = sps ~ SPoint.create(2,4);  //Internal error: ..\ztc\type.c 308
   SPoint sp = SPoint.create(2,4);  //This works
   sps = sps ~ sp;

   int[] a;
   a ~= 2;
   a = a ~ 2;

   foreach(p; sps)
     writefln(p.x,",",p.y);
}
