Hi to everybody, first of all I beg pardon if my English isn't much good: I'm Italian! I'm working with gcc 3.0.1 on a Linux Mandrake sys with kernel 2.4.8. The problem I'm having is that the second call of read_graphviz() in the same program causes a Segmentation fault. What can I do? Thank you in advance, Paolo PS Advices about the language are welcome too ;)
