Postincrement causes match problem - bug or feature?

["Andrew Bell" <andrew.bell.ia@xxxxxxxxx>]

Hi,

The following code gives a function match error.  If the postincrement
is removed on cp when calling foo(), everything is fine.  Is this a
compiler problem or a user problem?

Thanks:

=================

#include <iostream>

using namespace std;

template <typename T>
int foo(T& t1)
{
  cerr << "Got in #1!\n";
  return 0;
}

int foo(char* & c)
{
  cerr << "Got in #2!\n";
  return 0;
}

int main()
{
  char c = 'c';
  char* cp = &c;

  foo(cp++);
  return (0);
}

==============

test2.cc: In function 'int main()':
test2.cc:23: error: no matching function for call to 'foo(char*)'
test2.cc:6: note: candidates are: int foo(T&) [with T = char*]
test2.cc:12: note:                 int foo(char*&)
