Last minute change in Lambda syntax or gcc bug?

I use the svn-version of the gcc-4.7.0 to check out some C++11 features, e.g. Lambda Expressions. Since a couple of weeks some of my old examples including Lambdas to not compile anymore. I wonder:

• Did I miss a last-minute change in the C++11-Lambda-spec that has been implemented in gcc-4.7.0 in the last weeks?
• Is it a bug in gcc, that does not recognize inline-Lambdas anymore?
• Or did I misunderstood something else with Lambda-syntax?

The problematic code seems to involve inline-Lambdas that are provided as arguments directly.

Would you say that the following code is correct C++11 code?

#include <thread>
using namespace std;

struct Image {}; // dummy

void fill(int color, const Image& image) {
} // dummy

int main() {
    int red;
    Image img;
    thread th{
        [&img](int c){ fill(c, img); },  // error?
      red };
    th.join();
}

If I change it and assign the Lambda to a variable first it works:

#include <thread>
using namespace std;

struct Image {}; // dummy
void fill(int color, const Image& image) {
} // dummy

int main() {
    int red;
    Image img;
    auto f = [&img](int c){ fill(c, img); }; // lambda
    thread th{ f, red };                     // ok now
    th.join();
}

I put an example here where both compiles with gcc-4.5 (except that it raises an exception, probably because -pthread is not linked). But as I said: In my gcc-4.7.0-svn the first variant stopped compiling a couple of weeks ago.

Update The error message seems to be a parse error:
