Identical global variable declaration appearing in different translation units

t1.cpp

1  static int v = 11;
2
3  void g1()
4  {
5      v;
6  }

t2.cpp

1  static int v = 22;
2
3  void g2()
4  {
5      v;
6  }

The compiler I used parses t1.cpp and t2.cpp at once into ROSE AST. Then it takes each SgVarRefExp node (reference to 'v' at line 5) from all function body and finds its SgInitializedName node via the following pseudocode:

SgVarRefExp *ref;
SgInitializedName *name;
...
name = ref->get_symbol()->get_declaration();

It firstly obtained the correct SgInitializedName node for the 'v' declaration in t1.cpp from the 'v' reference in t1.cpp, but later from the 'v' reference in t2.cpp it wrongly got the 'v' declaration in t1.cpp.

(gdb) p ref
$8 = (SgVarRefExp *) 0x7fffe492b010
(gdb) p name
$9 = (SgInitializedName *) 0x7fffe4cca5b0

(gdb) p ref
$10 = (SgVarRefExp *) 0x7fffe492b078
(gdb) p name
$11 = (SgInitializedName *) 0x7fffe4cca5b0

Different address for 'ref', but same address for 'name'.
