"I'll just disable the watchdog for now while I test this code. I'll remember to enable it in the release version"
Since (most?) ICEs do not like the watchdog, I have a conditional compile flag (DEBUG_MODE) that does the above and set the various flags required for ICE. In addition, if that flag is set, the executable get another name. Thus, no such mistake is possible - production would come running "what model is this software for?" if I gave them SW with the 'debug name'.
