Compute shader: Unexpected results when accessing const array of 64-bit integers

I have a simple compute shader:

#version 450 core

#extension GL_ARB_gpu_shader_int64: require

#define STATE_SIZE_UINT64 25 /** 200 bytes */

layout(binding = 0) buffer writeonly State {
  uint64_t st[];
};

const uint64_t RC[4] = {
    0x0000000000000001UL, 0x0000000000008082UL,
    0x800000000000808aUL, 0xf123456789abcdefUL
};

void main()
{
  uint index = gl_GlobalInvocationID.x;

  uint sti = index * STATE_SIZE_UINT64;

  uint i = 3;
  st[sti] = RC[i];
  return;
}

After executing the shader I expect first 8 bytes of buffer to be:

0xefcdab89674523f1

but instead I am getting:

0x00d0ab89674523f1

If I rewrite shader code to access constant directly:

...
  st[sti] = RC[3];  
...

then it works fine.

System: Arch Linux
Kernel: 4.15.10
Nvidia driver: 390.42
GPU: NVIDIA Corporation GK208 [GeForce GT 730] (rev a1)
Shader compiler: Glslang Version: 6.5.2629

Tried it on GeForce 1080Ti - same problem persist
Tried on AMD GPU (RX570) - works as expected
