This also occurs in version 2.27.20100201.0545.
I eliminated a large portion of the graph. Let me know if you want the full file.
I have seen dot crash on previous versions of the input, but have been able to work around it before by re-ordering the input. Haven't been able to find a re-ordering that works this time.
The line that causes the issue: kcmrisk01_LoadDataModel -> kcmapps03_RunSecurityForge; Comment it out and it runs. Uncomment the lines immediately above it and it still runs.
Similarly, if you exclude the bad line above and include: // tjm303risk01_LoadDataModel -> kcmapps03_RunSecurityForge; it also crashes.
Something about kcmapps03_RunSecurityForge as a target?
