Summary0000432: Init_rank trouble with clusters
Description



The following DOT graph produces the subject error message.
I swap the first 2 edge pairs and it complete successfully.
Alternatively, if a uncomment the mclimit=5.0, it completes successfully.
Obviously, this is a simple test. I have a much more complex case (100+
edges)
which produces the same error for mclimit=50.0.
