Catching possible bugs

• Types of indicators of bugs and detection of them:
  • Invalid memory access -> #PF interception and nested page fault
  • Use of a non-canonical form memory address -> #GP interception
  • Valid but bogus code execution -> #UD and #BP interception
  • Dead loop -> Timer expiration
• Exploration of those ideas are left for readers
  • The author has not discovered non-dead-loop bugs
