I am implementing Kosaraju's Strong Connected Component(SCC) graph search algorithm in Python.

The program runs great on small data set, but when I run it on a super-large graph (more than 800,000 nodes), it says "Segmentation Fault".

What might be the cause of it? Thank you!

Additional Info: First I got this Error when running on the super-large data set:

"RuntimeError: maximum recursion depth exceeded in cmp"

Then I reset the recursion limit using

sys.setrecursionlimit(50000)

but got a 'Segmentation fault'

Believe me it's not a infinite loop, it runs correct on relatively smaller data. It is possible the program exhausted the resources?
