  Log:
    re_pattern_buffer: shrink from 464 to 448 bytes on 64-bit
    
    * include/ruby/oniguruma.h (struct re_pattern_buffer): shrink to 448
      bytes from 464 bytes on 64-bit.  This breaks the ABI.
      [Feature #10034]
    
    Reducing struct re_pattern_buffer from 464 to 448 bytes allows it to fit
    into neatly into seven 64-byte cache lines on x86-64 systems.
