I don't know which software you may be referring to, but Komodo at least saves files before launching the debugger. Although Komodo had a propensity (now resolved) to lock up or crash during debugging I've never lost any work as a result, just a little time and nothing like as much time as the debugger has saved.

True laziness is hard work
