Yusuke Endoh e9a4cc02b4 [ruby/error_highlight] Add a test to check if it is robust against a spoofed filename ... Previously, RubyVM::AST.of opened a wrong file if the iseq's file path is spoofed. ``` module Dummy binding.irb end ``` ``` $ ruby test.rb From: test.rb @ line 2 : 1: module Dummy => 2: binding.irb 3: end irb(Dummy):001:0> foo /home/mame/work/ruby/local/lib/ruby/3.1.0/error_highlight/base.rb:412:in `spot_colon2': undefined method `last_lineno' for nil:NilClass (NoMethodError) if nd_parent.last_lineno == @node.last_lineno ^^^^^^^^^^^^ ``` Found by @kateinoigakukun This issue is already fixed in the interpreter side. This change just adds a test for the case. f3626b9032		2022-01-04 23:18:37 +09:00
