The root cause is bug 6336, and was already fixed in 2.061head.

OP sample now works. If there is some other compiler problem please file a new
bug (I don't see this error either "std/array.d(460): Error: a[0u] isn't
mutable").

Thank you for your reduction.
Then I have modified the 'component' of this bug report from Phobos to DMD.

This problem reduces to the following case,
where dmd rejects ref to struct type with a const field, with error:
std/array.d(460): Error: a[0u] isn't mutable

I think this is a compiler bug.



import std.array;
struct A {
   const(char) c;
}
void main() {
   A[] aa;
   aa.front;
}

// ref T front(T)(T[] a)
// if (!isNarrowString!(T[]) && !is(T[] == void[]))
// {
// assert(a.length, "Attempting to fetch the front of an empty array of " ~
//  typeof(a[0]).stringof);
// return a[0];  // ** std/array.d(460)
// }
