 The Crashpad backend on macOS doesn't currently support notifying the crashing process and thus can't correctly terminate sessions or call the registered `before_send` or `on_crash` hooks. It will also lose any events queued for sending at the time of the crash.

+
+The Crashpad backend on Windows supports fast-fail crashes, which bypass SEH (Structured Exception Handling) primarily for security reasons. `sentry-native` registers a WER (Windows Error Reporting) module, which signals the `crashpad_handler` to send a minidump when a fast-fail crash occurs. But since this process bypasses SEH, the application local exception handler is no longer invoked, which also means that for these kinds of crashes, `before_send` and `on_crash` will not be invoked before sending the minidump and thus have no effect.
