Don't know if this is even related to your problem or not but, again, I figured it couldn't hurt to post just in case.
As you probably know if you've spent more than a coffee break's worth of time installing software, setting options is a procedure unto itself. In this case, Dev-C++ has two options that must be set before you can use it. Set 'em as follows:
1. Choose tools->Compiler Options.
2. Choose the Settings tab.
3. Choose Code Generation from the menu on the left. Make sure that the Enable Exception Handling is enabled... if it isn't, click on the option box to display the two choices and select Yes.
4. Choose Linker and make sure the Generate Debugging Information option is enabled.
5. Choose Ok.
