[New-bugs-announce] [issue30973] Regular expression "hangs" interpreter

[T Trindad]

New submission from T Trindad:

The following code "hangs" the interpreter:

    import re
    re.search(r"/\*\*((?:[^*]+|\*[^/])*)\*/", """	/** Copy Constructor **/
	private EvaluationContext (EvaluationContext base) {""")



Changing the regex to r"/\*\*((?:[^*]|\*[^/])*)\*/" makes it work normally.
