; In the following logical views, we can see that the DWARF debug
; information generated by the Clang compiler shows the variables
; 'Var_1' and 'Var_2' are at the same lexical scope (4) in the function
; 'InlineFuction'.
; The DWARF generated by GCC/Clang show those variables at the correct
; lexical scope: '3' and '4' respectively.
