This reminds me of a C program I once saw. Certain functions in the code were dependent on the stack order. If you moved any thing around the (10mm+ LoC) app would fail to compile. Therefore any time anyone wanted to change these functions they would just append more code to the bottom, never touching any of the existing code. Most of it was garbage, but if you touched it at all, everything would break.
