--- Comment #5 from Markus Trippelsdorf <markus at trippelsdorf dot de> 2012-10-11 16:45:51 UTC ---
The testcases could be a bit further reduced:

markus@x4 testcase % < test.i
typedef wchar_t;
wchar_t a;
markus@x4 testcase % < test.ii
class P
{
public:
    typedef int PCXSTR;
    typedef wchar_t YCHAR;
};
class F
{
    P::PCXSTR PCXSTR;
};
class M
{
    bool OnHashAlg (const wchar_t *);
    F m_sPubKeyAlgOID;
};
bool
M::OnHashAlg (const wchar_t *)
{
}
markus@x4 testcase % gcc -r -nostdlib -flto test.i test.ii
lto1: internal compiler error: in uniquify_nodes, at lto/lto.c:1873

and with your gcc_asserts applied:

markus@x4 lto_bug % < test.i
typedef wchar_t;
wchar_t a;
markus@x4 lto_bug % < test.ii
void
fn1 (const wchar_t *)
{
}
markus@x4 lto_bug % gcc -r -nostdlib -flto test.i test.ii
lto1: internal compiler error: in write_ts_type_common_tree_pointers, at
tree-streamer-out.c:615
