+ *
+ * # Parameters
+ * - `error_type`: Optional type/class of the exception (e.g. "NullPointerException"). Pass empty
+ *   CharSlice for unknown.
+ * - `error_message`: Optional error message. Pass empty CharSlice for no message.
+ * - `runtime_stack`: Stack trace from the runtime. Consumed by this call.
+ *
+ * If the crash-tracker has not been initialized, this function is a no-op.
+ *
+ * # Side effects
+ *   This function disables the signal-based crash handler before performing
+ *   any work. This means that if the process receives a fatal signal (SIGSEGV)
+ *   during or after this call, the crashtracker will not produce a
+ *   second crash report. The previous signal handler (if any) will still be
+ *   chained.
+ *
+ * # Failure mode
+ *   If a fatal signal occurs while this function is in progress, the calling
+ *   process is in an unrecoverable state; the crashtracker cannot report the
+ *   secondary fault and the caller's own signal handler (if any) will execute
+ *   in a potentially corrupted context. Callers should treat this function as a
+ *   terminal operation and exit shortly after it returns.
+ *
+ * # Safety
+ *   Crash-tracking functions are not reentrant.
+ *   No other crash-handler functions should be called concurrently.
+ *   The `runtime_stack` handle must be valid and will be consumed.
