This is reduced from issue 10463.

struct DirIterator
{
    int _store = 42;
    ~this() {assert(_store == 42);} // line 4
}

DirIterator dirEntries()
{
    throw new Exception(""); // line 9
}

void main()
{
    /* This triggers only line 9: */
    version(A) DirIterator a = dirEntries();

    /* This triggers both lines 9 and 4: */
    else version(B)
    {
        DirIterator b = void;
        b = dirEntries();
    }

    /* With 'for' it looks like A, but behaves like B: */
    else for(DirIterator c = dirEntries(); true;) {}
}

I didn't dig this, but it looks like a dup of issue 8563

Does that patch fix issue 8563 or is this issue not a proper duplicate of 8563?

Because I couldn't reproduce segfault in Windoes 7 64bit (== 32bit codegen) environment. Right now I don't have x86_64 environment, so currently I don't have enough confidence that the PR fixes bug 8563...
