Looks fixed in 4.4.1.

Indeed, so I'll close this.
4.4 gives
const char* D<U>::foo(typename B<U>::X) [with U = int]
and 4.6 gives
const char* D<U>::foo(typename B<U>::X) [with U = int, typename B<U>::X = int]

Could you add a testcase before closing so we don't regress? I propose:

------- Comment #9 from redi at gcc dot gnu dot org  2010-06-06 11:17 -------
Are we sure we'll always want the "typename B<U>::X = int" part?
Would checking for just "const char* D<U>::foo(typename B<U>::X)" be
preferable?
(I don't know what the convention is for this sort of check)

I don't care as long as there is a testcase that tests for this bug. Bugs
shouldn't be closed if a testcase has not been committed that prevents
regressing.

OK, I see. I concede that they may be related. I was surprised by 
the fact that run-time and compile-time things should be the same, 
but __PRETTY_FUNCTION__ is of course filled at compile time. I had 
believed that this PR may be a demangler problem. 
 
Let's keep both of them open, if someone comes around to fix 
one of them, she can check the other one as well.

Reading what Christian Ehrhard (the last real comment) had to say causes me to think this is the same 
bug.

I am not convinced this is the same problem. Andrew, what reasons do you 
have to believe that this is the same bug?

This problem is caused by the same problem which PR 99 is caused by.  Closing as a dup.

Confirmed indeed. Though the error is not that it doesn't show the 
value of T in 
  const char* D<U>::foo(typename B<T>::X) [with U = int] 
but that it decides to assign two different symbols 'U' and 'T' to the 
template parameters, where there is really only one template parameter 
around. They need to be printed with the same symbol.
