Subject: [ruby-changes:33776] nobu:r45854 (trunk): vm_eval.c: valid name IDs only
nobu 2014-05-07 13:26:49 +0900 (Wed, 07 May 2014) New Revision: 45854 http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=45854 Log: vm_eval.c: valid name IDs only * vm.c (vm_collect_local_variables_in_heap): use struct local_var_list instead of VALUE directly. * vm_eval.c (local_var_list_update): add valid name IDs only.
