           Summary: Cannot use struct .init when it contains a static
                    array initialized from a single element.
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: rejects-valid
          Severity: regression
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: Marco.Leise gmx.de



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.
