Presumably, you are getting the vertices as triangles ?

If you are, and they are in sequential order, the indices are simply (0,1,2,etc.), 
the only crash i received when doing tri meshes, was in fetchtriangle, and i 
finally tracked it down to the fact that the index and vertex lists that you 
supply to the build function are required by it afterwards, i.e. it doesn't make 
its own copies. I was freeing them up after feeding them in, it found freed 
memory and crashed.
