[Dev-C++] Debugger not working? 4.9.8.7

[Emiliano <sky...@fa...>]

As in the subject, it won't work at all on my winxp system. The project gets
compiled, the debugging window is there, but no "step" button does what it
should, the step-by step execution doesn't start. In the output of gdb I've
noticed this:

frames-invalid

What is the last version with debugger know to work?
