VA build 2048, VS2008
Using a reference to a template parameter as the return type for a function appears to confuse the VA parser:
class C
{
public:
template<class T>
struct D
{
int i;
};
template<class T>
T& f(const D<T>& d);
int g();
int j;
};
template<class T>
T& C::f(const D<T>& d)
{
return d.i;
}
int C::g()
{
return j;
}
The D and d in C::f are underlined, and even the j in C::g (and every other function following C::f in the file) is not recognised.
If I remove the & from the return type there is no problem. |

I tried your sample code but unfortunately, I wasn't able to reproduce the problem. So I will ask more question which may shed some light to the problem.
1. Can you please try creating a clean new win32 test project to see if you are able to reproduce the problem by copy-pasting this code there?
Are you seeing the problem now?
2. Which extension are you using for your file where it happens? (I tried .cpp and .h)
3. Are you using any other Visual Studio extensions?
4. Are you using C++ or C++/CLI (CLR)?
5. Can you please move the caret over the j in the C::g() method? |

1. I created a new empty Win32 console project, added a file (main.cpp), pasted the code in and typed a space (to trigger the parser) and after a couple of seconds the red underlines appeared.
2. .cpp
3. SourceGear Vault plugin (not using it but it is installed). CodeJock Xtreme Toolkit. I have had the Qt extension installed, but I have since removed it.
4. C++
5. It shows the refactoring menu with the option to create a variable j. |

This is odd. Since this is happening at the parser level (e.g. unrecognized j), other extensions shouldn't matter. My 5th question was incomplete, but your answer was still helpful  The option to create a variable j suggests that VA does not recognize the variable.
If the problem also happens in a new project, I should be able to reproduce...
First, can you please try rebuilding your symbol databases?
VA Options -> Performance -> Rebuild
Does it make any difference?
If you're still seeing the problem in your test solution, can you please send it in along with your exported settings, to see if I can reproduce the problem using them?
1. VA Options -> Performance -> Export Settings
2. IDE tools menu -> Import and Export Settings -> Export selected environment settings
3. Zip up the solution
4. Send in the 3 files using the below form:

Please paste the URL of this topic to the "Your Request" field so we can match it up. |

Sorry for sending you on a wild goose chase. It turns out that a few more factors are needed to trigger the problem. I was misled by the fact that once the problem occurs, it remains even if the cause is removed, sometimes until VS is restarted and sometimes until the symbol database is rebuilt.
I have sent a modified solution which exhibits the problem, and the settings files. Note that I have the boost include directory in my "Stable include files". If I take it out, the problem goes away. |

Thank you for the files and the explanation. I was now able to reproduce the problem:

template parameter as return type confuses VA
