The following code works at runtime, but fails when initialized with a literal:

------------------
struct Bug7940 {
    int m;
}

struct App7940 {
   Bug7940[] x;
}

int bug7940() {
  Bug7940[2] y = [Bug7940(),Bug7940()]; // this line causes the failure
  //Bug7940[2] y;    // works
  App7940 app;
  app.x = y[0..1];
  app.x[0].m = 12;
  assert(y[0].m == 12);
  assert(app.x[0].m == 12);
  return 1;
}

static assert(bug7940());   // fails CTFE

void main()
{
    assert(bug7940());  //  works at runtime
}

Reduced test case
--------------

struct Bug10298 {
    int m;
}

int bug10298()
{
    Bug10298[2] y = [Bug10298(), Bug10298()];
    y[0].m = 6;
    assert(y[0].m == 6);
    return 1;
}

static assert(bug10298());

https://github.com/D-Programming-Language/dmd/commit/dfcaed6cd55f5bbaa121788fbf256e07f7e47a20 Fix bug 10298 CTFE wrong code for struct array literal init

The elements in an array literal need to have constness implicitly cast away when they are being slice assigned.
