The problem really is that _NSIG is bogus, it is actually the number of
signals plus one. That doesn't change the value of __NSIG_WORDS, but if
there would actually be 65 signals then __NSIG_WORDS would be too small.
Note also that mips has the wrong value for __SIGRTMAX (it should be
128).
Andreas.
