I am experiencing the same issue with radeonsi. It supports OpenGL 4.1. It crashes right away. When I override OpenGL version to 4.2, it goes to play a initial logo sound, but there is no video and one of the threads crashes in OpenGLRenderer::ApplyConstants() function. I disassembled this function in gdb. Notice the line starting with =>, that is where the crash occurs.

When analysing the control flow, you can clearly see that there is possible NULL pointer dereference.
Code
//0x00007ffff48467eb:
  eax = this->variable_at_offset_0x6f8
//0x00007ffff48467f2:
  rcx = some_related_global_or_static_variable
//0x00007ffff48467fb:
  if (eax != rcx) {
    // 0x00007ffff4846801:
    r15 = NULL
    if ((eax & 0x3ff0000) != 0) {
       // ...
       // r15 is set in this block to valid value
       // ...
    }
    // 0x00007ffff4846845:
    rcx = r15->variable_at_offset_0x10 // crash here because r15 can be NULL
  }
// function end


This is bug in game code.
