[Bug libstdc++/18808] New: iostream include makes algorithm/transform broken

[kgardas at objectsecurity dot com]

Hello,

using gcc3.4.2, following code compiles well:

       1 
       2 #include <cctype>
       3 #include <string>
       4 #include <algorithm>
       5 //#include <iostream>
       6 
       7 using namespace std;
       8 
       9 int
      10 main() {
      11 string s="HeLLO";
      12 transform(s.begin(), s.end(), s.begin(), tolower);
      13 return 0;
      14 }
      15 

but when I uncomment iostream include on line 5, it starts to be broken:

$ c++ str.cc 
str.cc: In function `int main()':
str.cc:12: error: no matching function for call to
`transform(__gnu_cxx::__normal_iterator<char*, std::basic_string<char,
std::char_traits<char>, std::allocator<char> > >,
__gnu_cxx::__normal_iterator<char*, std::basic_string<char,
std::char_traits<char>, std::allocator<char> > >,
__gnu_cxx::__normal_iterator<char*, std::basic_string<char,
std::char_traits<char>, std::allocator<char> > >, <unknown type>)'
$ 

Although this code is perfectly compilable by Comeau C++ 4.3.3/Dinkumware 4.02
and Intel C++ 8.0.

Cheers,
Karel
