To reproduce:
1. Open project
2. Compile the two shaders 'broken' and 'working'
3. Compare compiled GLSL code(take a look at place where:
layout(std430, binding = 0) readonly buffer index_buffer {
index_buffer_type index_buffer_buf[]; )

Expected: binding will be set to 1
Actual: binding is reset to 0

Reproduced: 2017.1.4p2, 2017.2.3p2, 2017.3.2f1, 2017.4.6f1, 2018.1.8f1, 2018.2.0f2, 2018.3.0a4

Note: works properly on DirectX
