  New Revision: 59442

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=59442

  Log:
    compile.c: fix flip-flop value
    
    * compile.c (iseq_compile_each0): as compile_flip_flop always ends
      with a jump instruction, successive instruction is never reached,
      but caused stack consistency error without peephole optimization.

  Modified files:
    trunk/compile.c
