The code can be compiled with debugging information, you can then upload a debug version to a board via a JLink/St-Link debug adapter and step through the code in your IDE.
More information about the necessary hardware and setting up the eclipse IDE can be found here
A guide for visual studio can be found here: http://visualgdb.com/tutorials/arm/st-link/

Various debugging hardware solutions exist, the Segger J-Link clones are cheap and are known to work on Windows with both the Naze and Olimexino platforms.
Segger make excellent debuggers and debug software.
The Segger J-Link GDB server can be obtained from here.

STLink V2 devices
STLink V2 devices can be used too, via OpenOCD.

DEBUG=GDB make argument.
You may find that if you compile all the files with debug information on that the program is too big to fit on the target device. If this happens you have some options:
- Compile all files without debug information (
make ...), then re-save or
touchthe files you want to be able to step though and then run
make DEBUG=GDB. This will then re-compile the files you're interested in debugging with debugging symbols and you will get a smaller binary file which should then fit on the device.
- You could use a development board such as an PORT103R, development boards often have more flash rom.
Install OpenOCD via Brew
