Ariane 5G

  • During its maiden voyage it crashed due to a buffer overflow
    • Used coded from the Ariane 4
      • Assumptions were correct for the Ariane 4 but not the Ariane 5 trajectory
    • Tried to convert data from 64-bit floating point --> 16-bit signed integer
      • Caused an overflow
    • Programmers only wrote code to protect four out of seven critical variables from overflowing
