[ruby-core:117368] [Ruby master Bug#20401] Duplicated when clause warning line number

Issue #20401 has been reported by kddnewton (Kevin Newton). ---------------------------------------- Bug #20401: Duplicated when clause warning line number https://bugs.ruby-lang.org/issues/20401 * Author: kddnewton (Kevin Newton) * Status: Open * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- When you have a duplicated when clause, you get a warning for it. For example: ```ruby case foo when :bar when :baz when :bar end ``` you get `warning: duplicated `when' clause with line 2 is ignored`. But the when clause that is ignored is the one on line 4, not line 2. It seems like it's warning for the wrong line. -- https://bugs.ruby-lang.org/
