main.cpp and shader.

Hello.
I can't assign a variable with the data from shared storage. Before 17.2.5 =
this
bug affected all storage types, when using loops. It was fixed. Now its with
shared storage only. Some algorithms are impossible to implement efficientl=
y.
I've created a test app to reproduce this bug.
Output should be:
OUTPUT: 2101479989,1917184202,4191109983,1779160146
Currently it is:
0,0,4191109983,1779160146

It was also tested with AMD proprietary driver(GL_AMD_gpu_shader_int64) on
Windows 10 and worked correct.
Note 1: If you remove a "shared" qualifier inside shader, you wil=
l see a
correct output.
Note 2: Sometimes an app freezes my OS on Shader Program execution.
