  New Revision: 61541

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=61541

  Log:
    suppress warning for clang
    
    In this function, "volatile" is specified twice in macro-expanded
    `VAR_INITIALIZED(cont)` part.  That is a problem in fact.  However
    I don't want to touch this line because it is already a messy
    workaround for clang SEGV.  Let me just ignore.
