Does a failure of a trial court to ask a defendant represented by an attorney whether he has anything to say before sentence is imposed under the writ of habeas corpus?

"The failure of a trial court to ask a defendant represented by an attorney whether he has anything to say before sentence is imposed is not of itself an error of the character or magnitude cognizable under a writ of habeas corpus. It is an error which is neither jurisdictional nor constitutional. It is not a fundamental defect which inherently results in a complete miscarriage of justice, nor an omission inconsistent with the rudimentary demands of fair procedure. It does not present 'exceptional circumstances where the need for the remedy afforded by the writ of habeas corpus is apparent.' Bowen v. Johnston, 306 U.S. 19, 27."
