attaching testcase.
result should be '1', but is '2', an int is matched to a pointer.
(and the pointer has the value of the integer in the function)
is known to fail for 3.3.5 and 3.4.4.
I can't test with 4.0 atm but I think it also fails because I came across this
by a strange internal tree generated by 4.0.

Comeau C++ thinks this code is invalid.
If it's right, this bug might be related to #20157

I believe the code is invalid: you try to do a partial specialization of
a member function, but there is no such thing -- you need to use an overload
instead. To me this looks like an accept-invalid. Here's what icc has to
say:
g/x> icc -Xc -ansi -c x.cc
x.cc(10): error: declaration is incompatible with function template "void
A<AT>::function(T) [with AT=int]" (declared at line 5)
void A<int>::function(TTT *){std::cerr << '2';}
^
x.cc(16): warning #592: variable "b" is used before its value is set
a.function(b);
^
compilation aborted for x.cc (code 2)
This also seems like a regression to me, since gcc2.95.3 gives me this:
g/x> /home/bangerth/bin/gcc-2*/bin/c++ -c x.cc -ansi -pedantic
x.cc:10: template parameters specified in specialization
x.cc:10: prototype for `void A<int>::function(TTT *)' does not match any in
class `A<int>'
x.cc:5: candidate is: template <class T> void A<int>::function<T>(T)
x.cc: In method `void A<int>::function(TTT *)':
x.cc:10: must specialize `struct A<int>' before defining member `void
A<int>::function(TTT *)'
x.cc:10: template definition of non-template `void A<int>::function(TTT *)'
