  New Revision: 15099

  Modified files:
    trunk/ChangeLog
    trunk/encoding.c
    trunk/parse.y

  Log:
    * parse.y (parser_initialize): explicitly call rb_ascii8bit_encoding().
    
    * parse.y (parser_prepare): lex_input may not be have encoding (e.g. IO).
    
    * parse.y (rb_parser_compile_string): set encoding from input string. 
    
    * encoding.c (rb_enc_find_index): use ASCII-8BIT if loading known
      encoding failed.
