  • Security Issue
    • buffer overflow
    • integer overflow(signed → unsigned)
• Why not GC’ed language?
  • downsides of GC
    • Expensive
    • Disruptive
    • Non-deterministic
    • Precludes manual optimization
  • can not solve memory leak completely

  • Dangling Pointers
  • Double Frees
  • Iterator Invalidation
  • Memory Leaks
• Ownership Rules
