Hello.

I'd like to know how to refer values of variables. My understanding is all of variables are seen in a variable scope when I stop a program, but at the moment, I can't look at some variables I defined. Could someone teach me how to figure out the problem ? Regards

Use optimization level 0 (-O0).
