Bug #20421
Updated by andrykonchin (Andrew Konchin) about 1 month ago
When String#index and String#byteindex are called with Regexp and offset they clear `$~` (that contains result of the last Regexp matching) when offset < -size. But they don't clear `$~` when offset > size what seems inconsistent: not consistent: ```ruby "a".index(/a/) p $~ # => #<MatchData "a"> string = "blablabla" string.index(/bla/, string.length + 1) p $~ # => #<MatchData "a"> ```
