[ruby-core:111676] [Ruby master Bug#19312] SEGV during test_ast.rb: <internal:ast>:76: [BUG] parser_token2id: unknown token -1

6 Jan 2023

      Issue #19312 has been updated by nobu (Nobuyoshi Nakada).

https://github.com/ruby/ruby/pull/7077
Maybe old versions should use `END_OF_INPUT` instead of 0 and -1.
