What is a crash reporter?
- Enables developers to analyze crashes that occur in the wild
- Produces stack backtraces that help identify how a program failed
- Offers higher-level data aggregation (topcrashes, MTBF statistics)
Motivation
- Talkback is proprietary and unmaintained
- Smaller open-source projects have few options
- Larger projects need flexibility and scalability
Design Options
- Stackwalking done on client
- Apple CrashReporter
- GNOME BugBuddy
- Client sends memory dump

- Windows Error Reporting
- Breakpad
