Subject: [ruby-talk:14275] Possible minor bug in io.c


I _think_ there may be a bug in set_outfile:

     static void
     set_outfile(val, var, orig, stdf)
         VALUE val;
         VALUE *var;
         VALUE orig;
         FILE *stdf;
     {
         OpenFile *fptr;
         FILE *f;

         if (val == *var) return;

         if (TYPE(*var) == T_FILE) {
             rb_io_flush(*var);              // <<<<<<<<<<
         }


I think this should check to see if the file is closed before doing
the flush. 

     begin
       $stderr.close
       $stderr = nil
     rescue
       puts "Exception"
       puts $!
       puts $!.backtrace
     end

  #=>

     Exception
     closed stream
     t.rb:3


However, I may well be wrong... :)
