  New Revision: 66269

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=66269

  Log:
    convert check for array length to assertion and comment out
    
    In regparse.c, in function node_extended_grapheme_cluster,
    we used a raw if() with exit(1) as a cross-check for our
    length calculations for the common node array. Convert this
    to an assertion and comment it out because it is not needed
    for active code.
