[igraph] Segmentation fault in setting attributes in class based programming (c++)

Dear all,
I'm currently using C-igraph to study users surfing specific networks. I

use some attributes to identify the nodes of my networks. An igraph_t
variable is a protected data member of a particular class. Trying to set
the attributes (with functions like SETVAB, SETVAN) in one constructor of
the class, I get a segmentation fault.

I put "igraph_i_set_attribute_table(&igraph_cattribute_table);" at the

beginnig of the main.

If I try to set attributes to an igraph_t variable in the main (and not

to a igraph_t datamember of a class) everything's ok.

What is wrong with setting atributes of a graph in the constructor of a

class?

Thank you in advance
Giovanni Paleari
