Windows message says: Unknown software exception (0xc00000fd) exception happened at 0x004477f3.

Memory used just before the crash is near 64Mb, and both computers I used has more than 1G memory.

This Digraph is mostly like a 100x100 square with two vertical edges by node (next2, prev2), and one horizontal edge by node (join).

With a 10x10 graph, it doesn't crash.

May it be an hard codded bound, or an exponential memory allocation ? I'll get the source code and get it crash under debugger.
