It looks like an issue.
When I'm trying to access to static method from lambda defined in another method I'm getting following error:

Compilation finished with errors:
source.cpp: In lambda function:
source.cpp:7:22: error: 'this' was not captured for this lambda function


Sample code:
struct Test
{
   static void func1() {}
   void func2() 
   {
      auto f = []() {
         Test::func1();
      };
   }
};
int main()
{}

It's could be easily reproduced on gcc 4.7.3 and bellow.
I haven't checked iso standard for right behavior - but it seems msvc and clang compilers work fine with this example.
Also it gets ok when I pass this to lambda.
