--- Comment #13 from Arseny Solokha <asolokha at gmx dot com> ---
In decl_address_invariant_p() we hit this break:

 3423     case VAR_DECL:                                                        
 3424       if ((TREE_STATIC (op) || DECL_EXTERNAL (op))                        
 3425           || DECL_THREAD_LOCAL_P (op)                                     
 3426           || DECL_CONTEXT (op) == current_function_decl                   
 3427           || decl_function_context (op) == current_function_decl)         
 3428         return true;                                                      
 3429       break;

and return false, which in the end becomes what is_gimple_min_invariant()
returns. I can provide relevant dumps or gdb session printouts if so desired.
At first glance I didn't notice anything glaringly wrong there, but admittedly
I have no idea what to look at.
