Title: Error with subgraph
Submitter: Andrea Talucci

Subsys: Dot
Version: 2.20.3
System: *-*
Severity: critical
Problem:
The graph graph_out.dot is not rendered (some msgbox suggesting to report bugs here...)

removing the section "subgraph ALTRO" resolves the problem. File graph_out.dot is self-produced... maybe some syntax error ?
Input file: b1516.dot
Comments:
removing the section "subgraph ALTRO" resolves the problem.

[erg] The problem is tied to rank=min along with edge labels. The actual crash occurs during positioning. Somehow the graph used for network simplex ends up with a cycle.

Here is a reduced graph exhibiting the problem.
