  New Revision: 30781

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=30781

  Log:
    * vm_core.h (GetThreadPtr): use TypedData_Get_Struct() instead
      CoreDataFromValue() because we need type check. Otherwise,
      type mismatch can cause segmentation fault crash.
      [ruby-core:35086] [Ruby 1.9-Bug#4367]
    
    * vm.c (thread_data_type): remove static.
