It's most certainly not that simple.  I haven't looked at the sources.
But the asm code does not really correspond to the code above.  The
function above is most certainly inlined.  The problem might very well
(and most likely is) in the use of this function.  Look at the

  cmELF::GetRPath()

function and where it directly or indirectly uses the Valid function.
