  Log:
    symbol.c: make dsym_fstrs an identity hash
    
    * symbol.c (Init_sym): make dsym_fstrs a hash compared by identity
      as the keys are unique fstrings, to get rid of running hash and
      compare methods and causing new object allocation during garbage
      collection phase.  [ruby-dev:48891] [Bug #10933]
