PS4 Tesselation compile error.

Using Unity 5.2.1p2 and SF 1.18. Unity won't compile a Tesselation shader for PS4. I actually found out that the problem is from the domain name definition which seems to confuse Unity.

#pragma domain domain

VertexOutput domain () {}

Using ds_surf as a domain name compiles and runs on PS4 :)

#pragma domain ds_surf

VertexOutput ds_surf () {}

Found the correct name from: inspecting the surface shader generated code from these shaders:
