  New Revision: 58902

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=58902

  Log:
    attempt to fix rb_alloc_tmp_buffer2 for ALLOCV_N
    
    This is a confusing function to my arithmetic-challenged mind,
    but nobu seems alright with this.  Anyways this lets me use
    large values of elsize without segfaulting, and "make exam"
    passes.
    
    * include/ruby/ruby.h (rb_alloc_tmp_buffer2): attempt to fix
