I'm still seeing the same segfault that I worked around in the patch on
#4505. Here is code that triggers it for me.
{{{
sage: import networkx.generators.atlas # long time
sage: atlas_graphs = [Graph(i) for i in
networkx.generators.atlas.graph_atlas_g()] # long time
sage: a = [i for i in [1..1252] if atlas_graphs[i].is_planar()] #
long time
sage: b = [i for i in [1..1252] if atlas_graphs[i].is_planar()] #
long time
}}}
I've added that as a doctest to the planarity code.
For me, the segfault usually happens on the second run (the "b =" line),
but occasionally happens on the first run.
