Error when generating graph

[davidjirovec]

When I try to generate graph for
digraph G { rankdir="LR" subgraph cluster_ORIGINATOR { DRAFT; } subgraph cluster_MRA_REVIEWER { PENDING_REJECT; PENDING_ASSIGN; DISCARDED; } subgraph cluster_MRA_PRIMARY_APPROVER { ASSIGNED; } subgraph cluster_MRA_SECONDARY_APPROVER { PENDING_DEPRECATE; APPROVED; DISALLOWED; APPROVED_AUTOMATICALLY; RETIRED; REJECTED; PENDING_RETIRE; PENDING_FINAL_REJECT; PENDING_APPROVE; PENDING_NOT_REQUIRED; DEPRECATED; PENDING_DISALLOW; } DRAFT -> PENDING_ASSIGN [label="SUBMIT"];DRAFT -> ASSIGNED [label="REWORKED_DRAFT_SUBMIT"];ASSIGNED -> PENDING_FINAL_REJECT [label="FINAL_REJECT"];ASSIGNED -> PENDING_DEPRECATE [label="DEPRECATE"];ASSIGNED -> PENDING_NOT_REQUIRED [label="NOT_REQUIRED"];ASSIGNED -> DRAFT [label="REVERT"];ASSIGNED -> DISCARDED [label="TERMINATE"];ASSIGNED -> PENDING_RETIRE [label="RETIRE"];ASSIGNED -> PENDING_DISALLOW [label="DISALLOW"];ASSIGNED -> PENDING_REJECT [label="REJECT"];ASSIGNED -> PENDING_APPROVE [label="APPROVE"];ASSIGNED -> ASSIGNED [label="SAVE_AS_DRAFT"];PENDING_REJECT -> ASSIGNED [label="REVIEWER_SUBMIT"];PENDING_REJECT -> DRAFT [label="REVERT"];PENDING_REJECT -> DISCARDED [label="AGREE_DISCARD"];PENDING_ASSIGN -> DRAFT [label="REVERT"];PENDING_ASSIGN -> ASSIGNED [label="REVIEWER_SUBMIT"];PENDING_ASSIGN -> DISCARDED [label="TERMINATE"];PENDING_NOT_REQUIRED -> APPROVED_AUTOMATICALLY [label="AGREE_NOT_REQUIRED"];PENDING_NOT_REQUIRED -> DRAFT [label="REVERT"];PENDING_NOT_REQUIRED -> DISCARDED [label="TERMINATE"];PENDING_NOT_REQUIRED -> ASSIGNED [label="RESET"];PENDING_APPROVE -> DRAFT [label="REVERT"];PENDING_APPROVE -> ASSIGNED [label="RESET"];PENDING_APPROVE -> DISCARDED [label="TERMINATE"];PENDING_APPROVE -> APPROVED [label="AGREE_APPROVE"];PENDING_FINAL_REJECT -> REJECTED [label="AGREE_REJECT"];PENDING_FINAL_REJECT -> DRAFT [label="REVERT"];PENDING_FINAL_REJECT -> DISCARDED [label="TERMINATE"];PENDING_FINAL_REJECT -> ASSIGNED [label="RESET"];PENDING_DEPRECATE -> DRAFT [label="REVERT"];PENDING_DEPRECATE -> DISCARDED [label="TERMINATE"];PENDING_DEPRECATE -> ASSIGNED [label="RESET"];PENDING_DEPRECATE -> DEPRECATED [label="AGREE_DEPRECATE"];PENDING_DISALLOW -> DRAFT [label="REVERT"];PENDING_DISALLOW -> DISCARDED [label="TERMINATE"];PENDING_DISALLOW -> DISALLOWED [label="AGREE_DISALLOW"];PENDING_RETIRE -> ASSIGNED [label="RESET"];PENDING_RETIRE -> DRAFT [label="REVERT"];PENDING_RETIRE -> DISCARDED [label="TERMINATE"];PENDING_RETIRE -> RETIRED [label="AGREE_RETIRE"];}

I get an error:

When I generate graph for same input using Graphviz dot.exe binary, it works ok.

I encountered the same error; perhaps another example helps pinning down the problem:

I get the error when trying to generate the following graph with dot:

digraph G{
    type="digraph";
    rankdir="TB";
    3->5[label="e1",color="#00cc00",constraint="false",fontcolor="#00cc00"]
    5->4[label="e2",color="#00cc00",constraint="false",fontcolor="#00cc00"]
    10->5[label="e3",color="#00cc00",constraint="false",fontcolor="#00cc00"]
    10->8[label="e6",color="#00cc00",constraint="false",fontcolor="#00cc00"]
    3->4[style="invis"]
    4->5[style="invis"]
    5->6[style="invis"]
    6->7[style="invis"]
    7->8[style="invis"]
    8->9[style="invis"]
    9->10[style="invis"]
    10->11[style="invis"]
    subgraph tokens{
        rank="same";
        3[label="t1",shape="box"]
        4[label="t2",shape="box"]
        5[label="t3",shape="box"]
        6[label="t4",shape="box"]
        7[label="t5",shape="box"]
        8[label="t6",shape="box"]
        9[label="t7",shape="box"]
        10[label="t8",shape="box"]
        11[label="t9",shape="box"]
    }
}

The stacktrace:

Graph generation works as soon as you remove one of the visible edges.

This is actually an instance of the bug reported in #65.
