Just this week we were porting some old c++ over to rust, stuff from the 90s probably. It was relying on the last element of an array being zero due to null termination. It used that value in its computation. That sounds crazy but fine, except it wasn't an array of bytes, so if it wasn't aligned and padded to 4bytes that last value might not be all zeroes. I don't know a common arch outside of microcontrollers where it wouldn't work, but still!
