digraph G

    nodesep = 1.5;

    rankdir = TB;
    ranksep = equally;

    { rank = same; A; B; }
    { rank = same; C; }
    { rank = same; D; E; }

    A -> B [label = 5];

    B -> C [label = 4];

    C -> B [label = 2];

Additional Information

This example only crashes with the edge labels. Without them, it does not crash.
Also, not all edge labels causes a segfault.
