-reduce Command prompt produces a segmentation fault

When trying to produce the dot graphs when running the dot command it produces a segmentation fault under the -reduce command.

Only difference found when comparing the toDot code with and without reduction is that the reduced code has shape=point, which is expected
Tobi’s new code to take in command line arguments checks out. It makes no changes internally, just calls the same function.
Was able to track down a source file of dot that I believe produces the error, I’m failing to understand the file though (and it may not be the right one) : https://fossies.org/linux/graphviz/lib/common/routespl.c . You can see the error message we are getting on lines 472 (which is oddly close to the 480 the error says it’s from) and 505. Is there a way to see the dot files that are installed on Onyx?
When running it as a job on R2 the error message changes, the second image below shows the message with the triangulation failed.
R2 runs version 2.30.1 of graphiz’s dot
Onyx runs version 2.40.1 of graphiz’s dot
Checking out to older code c59986b (August 18th) when I believe we could run all versions of the graph we get the same routeSplines error we have now.
