Re: [igraph] problem of igraph_degree_sequence_game() ?

[Gábor Csárdi]

Hi,

the problem is that the sum of the degrees is odd, there is obviously
no graph with the given degree sequence.

But thanks for reporting this, anyway, this is still a bug, igraph
should not crash, but give an error message. I'll correct it.

Thanks again,
Gabor
