GOTRACEBACK=crash is like “system” but crashes in an operating system-specific
manner instead of exiting. For example, on Unix systems, the crash raises
SIGABRT to trigger a core dump.
GOTRACEBACK=wer is like “crash” but doesn't disable Windows Error Reporting (WER).
For historical reasons, the GOTRACEBACK settings 0, 1, and 2 are synonyms for
none, all, and system, respectively.
