NVIDIA 310.90 'shared' qualifier bug

This compute shader works as expected:

Code :

---

#version 430 core
layout(local_size_x = 32) in;
shared int g_shared_data[32];
//...

---

This compute shader fails to compile with: 0(7) : error C0502: syntax error at token "shared"

Code :

---

#version 420 core
#extension GL_ARB_shader_storage_buffer_object : require
#extension GL_ARB_compute_shader : require
layout(local_size_x = 32) in;
shared int g_shared_data[32];
//...

---

Thanks.
