* compile.c (compile_array_): modify wrong optimization.
A script "[print(1)]; print(2)" should output "12". However, the compiler had eliminted "[print(1)]" expression because it is void expression (unused array). Of course, side-effect should be remained. This issue is reported by Masaya Tarui. * bootstraptest/test_literal.rb: add a test. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@38751 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
