This sample:

@trusted struct U
{
    this(this)
    {
    }
}

struct InvList
{
private:
    U data;
};

static InvList ivals()
{
    InvList list;
    //next line fails
    list.data = U.init;
    U a;
    //while this one works
    a = U.init;
    return list;
}

immutable foo = ivals();


Fails to compile with:
Error: CTFE internal error: unsupported assignment this = p
ctfe_this.d(18):        called from here: list.data.opAssign(U())
ctfe_this.d(24):        called from here: ivals()

Notice the first error without a line number.

Tested with lastest dmd from master.

Looks I'm stuck with it in the middle of reworking the core part of new std.uni.

My attempt to sidestep it by doing the same in constructor didn't work out.

Lovering severity as there is a workaround to construct data with __gshared + shared static this constructor. Not pretty but workable.

Was fixed somewhere during the 8 months since back then.
