The following code breaks GCC 4.7.1:
auto test = [=]() { this
Yes, I didn't paste that badly. That entire line of code alone by itself in the

Some more information is that this only seems to happen when the lambda
captures variables, and it's in the global scope.

The code in Bug 56464 is valid code:
struct bug { bug*a = [&](){return this;}(); };
(Just in case this may change the priority)
