Well, as I got gfortran binaries from http://www.equation.com/
I've contacted the Equation Team and they confirmed that that is a platform
specific bug. They addressed this bug and recommended to not use real128 float
numbers.

So I think that this bug report can be closed here. Thank you for the
attention.
