NaN position with splines=curved using neato

[sbliven]

I am having a problem with edges not showing up when using curved splines. This only seems to be a problem with neato, but I can't use the default filter because I need to set the node positions explicitly.

Input:

digraph "Assembly 2" {
        graph [
                splines="curved"
                size="1,1"
                dpi="300"
                ratio="fill"
                bgcolor="transparent"
        ]
        node [
                style="filled"
                fillcolor="#a6cee3"
                color="#a6cee3"
                width="1.5"
                regular="true"
                label=""
        ]
        edge [
                dir="none"
                penwidth="10"
        ]

    "A_0" [ pos="143.0,50.0" color="#1b9e77" fillcolor="#1b9e77"]
    "A_1" [ pos="50.0,550.0" color="#1b9e77" fillcolor="#1b9e77"]

    "A_0" ->"A_1" [ color="#000066" ]
}

When run with dot -Tdot -Kneato -O -n2 test.dot, I get the following output:

digraph "Assembly 2" {
    graph [bb="0,0,608,608",
        bgcolor=transparent,
        dpi=300,
        ratio=fill,
        size="1,1",
        splines=curved
    ];
    node [color="#a6cee3",
        fillcolor="#a6cee3",
        label="",
        regular=true,
        style=filled,
        width=1.5
    ];
    edge [dir=none,
        penwidth=10
    ];
    A_0  [color="#1b9e77",
        fillcolor="#1b9e77",
        height=1.5,
        pos="444.66,54"];
    A_1  [color="#1b9e77",
        fillcolor="#1b9e77",
        height=1.5,
        pos="163.34,554"];
    A_0 -> A_1   [color="#000066",
        pos="nan,nan nan,nan nan,nan nan,nan"];
}

The NaN edge position causes the edge to be dropped completely when rendered.

This is using graphviz version 2.38.0 (20140413.2041) on OS 10.11.4.

This was fixed in August, 2014. commit = 489f1a73936c7d0069defe6c23371ed4727644b1

Would you know in what version was that fix released?

[emden]

Since we build a new working version everyday, technically it would first be in graphviz-2.39.20140712. Any recent working version will have the fix. I'm not sure when we will produce a 2.40 stable release.
