 *  such mistakes, and the default (crashing) may be inadvisable.
 *  When this callback is triggered, the API function called is guaranteed not
 *  to cause a crash, though its return value and output arguments are
 *  undefined.
 *
 *  When this function has not been called (or called with fn==NULL), then the
 *  default handler will be used. The library provides a default handler which
 *  writes the message to stderr and calls abort. This default handler can be
 *  replaced at link time if the preprocessor macro
 *  USE_EXTERNAL_DEFAULT_CALLBACKS is defined, which is the case if the build
 *  has been configured with --enable-external-default-callbacks. Then the
 *  following two symbols must be provided to link against:
 *   - void secp256k1_default_illegal_callback_fn(const char *message, void *data);
 *   - void secp256k1_default_error_callback_fn(const char *message, void *data);
 *  The library can call these default handlers even before a proper callback data
 *  pointer could have been set using secp256k1_context_set_illegal_callback or
 *  secp256k1_context_set_error_callback, e.g., when the creation of a context
 *  fails. In this case, the corresponding default handler will be called with
 *  the data pointer argument set to NULL.
 *
 *  Args: ctx:  pointer to a context object.
