[Bonmin] error in running bonmin

[Giuseppe Aprea]

I see.

Any suggestion for a step by step debugging? I guess I am going out of
bound somewhere
but it's difficult for me to check; I usually write programs in python.....

maybe some compiler options? valgrind (in case, which options)?

thanks

giuseppe
