GraphViz.layout! command causes Malt.TerminatedWorkerException() #3128
Description
Reproducible example:
using GraphViz
g_dot_spec = dot"""digraph G {
rankdir="LR"
1 [label="{b | data -3.0 | grad -4.0 }"][shape="record"];
2 [label="{c | data 10.0 | grad -2.0 }"][shape="record"];
3 [label="{L | data -8.0 | grad 0.0 }"][shape="record"];
4 [label="*"];
5 [label="{f | data -2.0 | grad 4.0 }"][shape="record"];
6 [label="{a | data 2.0 | grad 6.0 }"][shape="record"];
7 [label="{e | data -6.0 | grad -2.0 }"][shape="record"];
8 [label="*"];
9 [label="{d | data 4.0 | grad -2.0 }"][shape="record"];
10 [label="+"];
1 -> 8;
2 -> 10;
4 -> 3;
5 -> 4;
6 -> 8;
7 -> 10;
8 -> 7;
9 -> 4;
10 -> 9;
}"""
above will work (although output is broken, JuliaGraphs/GraphViz.jl#38)
GraphViz.layout!(g_dot_spec, engine = "dot")
this causes the exception
