Description Andrew Gvozdev CLA 2011-09-01 12:09:32 EDT 
Consider following example:

x.hpp:
namespace ns {
   void fun();
}

x.cpp:
#include "x.hpp"
namespace alias = ns;
void alias::fun() {}

"alias::fun" is generating codan warning "Member declaration not found". F3 navigates to the definition in the header but not back. If I move namespace definition inside x.cpp everything starts working.
Comment 1 Markus Schorn CLA 2011-09-07 06:08:53 EDT 
Added testcase and fix.

Thanks for looking at it that soon but after this change an exception is thrown at following snippet after any change in the file:

template <typename T>
void f()
{
    typename T::type t;
}
