Have you tried generating any artificial network with the same number of edges? Or larger? If it does not crash, then I think there is something specific in your dataset that drives igraph crazy in a WinXP 64 bit environment. Debugging will be a challenge, though, since I use a Mac and Gabor uses Linux, but maybe he has access to some 64bit WinXP machines... at least I hope so :)

Hi dear developers,

I have just migrated my working environment to a 64 bit system.
One weird issue i encountered is i tried to initialize a graph with around 5k edges.
However, R will crash if I load around 3k edges.
For example,
if I use graph(el[1:1000,]), it is fine
if I use graph(el[1:3000,]), R will crash

I am now using R 2.6.2 with igraph. I not sure whether this is a igraph bug or R bug for the 64 bit system. If you have used igraph on windows XP 64 bit system please help!
thank you very much!
