    Use CRASH() in response to known, unrecoverable errors like out-of-memory.
    Macro is enabled in both debug and release mode.
    To test for unknown errors and verify assumptions, use ASSERT instead, to avoid impacting performance in release builds.
 
    Signals are ignored by the crash reporter on OS X so we must do better.
