Short description of error
Cycles layer weight node shows an incorrect result in Material mode in the viewport.
In 2.76, the attached file shows as follows:
While in 2.77-rc1 I get this:
Exact steps for others to reproduce the error

A workaround is to connect the Normal input of the Layer weight node to the Normal output of a Geometry node. However, connecting to a image texture normal map gives wrong results.

("Fix #47349: incorrect Cycles fresnel and layer weight with GLSL materials") fixes the problem for me. However, that does break the workaround described above (i.e. where the Normal output of the Geometry node is used).Changed status to: 'Open'

Thanks! However, it still gives an incorrect result when the layer weight has a Normal Map node as an input, e.g.:
In 2.76 the normal input had no effect in GLSL mode (i.e. the output looked like the first image above).
