I am receiving a abort signal from glibc when I am running the test
program that is attached. You will find that the program is suppose to
create a directed graph of five vertexes. I have printed out how the
edges are structured so you will have a picture of the graph. I hope
someone is able to help me figure out what is going wrong with this test
program. So far I am stumped as to what is wrong. Figuring out the
problem and its solution will help me figure out a much larger problem.
So the questions I have are:
1. Is there a problem with the definition of the graph?
2. Did I fail to do something in the initialization of the graph?
3. Is this the right forum for me asking my questions?
