Build Identifier: Build id: I20100312-1448

Initial condition: Empty C++ project where "string" was added to the "KEY_FILES_TO_PARSE_UP_FRONT" indexer properties and KEY_INDEX_UNUSED_HEADERS_WITH_DEFAULT_LANG was set to true. The project was then reindexed.

Code:
using namespace std;
string s;

Problem: even if the string type definition (which of course is in namespace std) is indexed, the indexer is not capable to resolve "string" in the given code (he is able to do so if "string s" is replaced with "std::string s").
The strange thing is that if one adds an empty namespace-definition to the code the resolution gets possible:

new code:
namespace std { }
using namespace std;
string s;

also strange: this problem is only present for the namespace std. consider the following code:
//main.cpp
using namespace X;
using namespace std;
string s;
MyStd s2;
MyX x;
//test.h
class MyC { };
namespace X { class MyX {}; }
namespace std {	class MyStd {}; }

Resoltion to MyX is possible here. Resolution to my own type added to std (std::MyStd) is not possible, same as string which is also not resolvable. When an empty namespace definition "namespace std { }" is added to the main.cpp the resolution of both string and MyStd gets possible.

Obviously, I would be most happy if the indexer would always be able to resolve std types (regardless of empty namespace definitions)

Reproducible: Always
