This change resolves an issue where Ada’s compiler raised a Program_Error exception when encountering ill-formed quantified expressions, particularly within pragmas such as Assert, Check, and Loop_Invariant. The fix involves removing unused code related to ‘Old attribute renaming and introducing a new procedure to detect and report these malformed expressions.
