[Dev-C++] Gtkmm/Dev-Cpp problem

[Jamiil <jal...@gm...>]

My program compiles, but it has a runtime error.
 I would like to backtrace the bug, but don't know how. After F8ing I =
don't get any output in Backtrace window. So, I guess it does not does =
it automatically. How can I get the backtrace displayed.
Thanks!
