Summary: simpexpt problem: sign called on imag arg

Initial Comment:
The expression (-(-1)^(1/6))^(1/2) gives the error
   SIGN called on an imaginary argument

This looks a lot like bug report 711885, except that in 
this case the expression causing the problem was 
generated directly from valid user input, not by another 
routine (in that case rootscontract) which created an 
incorrectly simplified internal result.
