Hello,

There is a reference to the original paper for the algorithm in the
GSL manual.  If there are any error bounds they should be described
there, but I don't believe the QR method provides a strict bound.   

Algorithms for guaranteed bounds aren't part of the current GSL,
although they do exist.
