The following code will generate a call to _d_arrayliteralT() for the struct
copy operation:


import core.stdc.stdlib;

struct List {}

struct GC
{
    List*[1] free_list;
}

void main()
{
    auto gc = cast(GC*) malloc(GC.sizeof);
    *gc = GC.init; // _d_arrayliteralT() called here
}

Probably a duplicate of bug 2356 or bug 4397.

It might be related but it's not a dup, because in those bugs, you actually are using array literals.  I don't see any array literal's in Sean's example.  In fact, there's no dynamic arrays anywhere.

There are no array literals in bug 4397 either. But maybe the same underlying cause because there seems to be something REALLY wrong how the compiler handles initializing structs with arrays in it, or array initialization.

const cX = X([1,2]);

that [1,2] sure looks like a literal to me...

Legitimately, you could say the compiler should be able to call _d_arrayliteralT once to initialize cX, but not call it every time cX is used.

But I think it's different than this bug.

This is now a duplicate of Issue 11345 because of fixing Issue 11238.
