Seeing is believing. Reduced test case: ____________________

import core.stdc.stdlib;

struct SZDDFile
{
    ExpandData* pExpandData = null;

    struct ExpandData
    {
        ubyte[4096] window = 0;
    }

    void open()
    {
        pExpandData = cast(ExpandData*) malloc (ExpandData.sizeof);
        *pExpandData = ExpandData.init;
    }
}
____________________

Error: cannot implicitly convert expression (cast(ubyte)0u) of type ubyte to
ubyte[4096LU]

It's not about the surrounding code, but rather, whether or not you use the .init property. Reduced test case:

//----
struct ExpandData
{
    ubyte[4096] window = 0;
}

void main()
{
    ExpandData a;
    auto b = ExpandData.init; //Comment me.
}
//----

Works in 2.061, so is a regression.

Right, came from the message boards, where you said "I didn't imagine it would depend on any surrounding code", and didn't notice you had already pinned it in the title.

Please ignore that sentence then.
