test case
I'm getting an internal compiler error both on gcc 4.7.0 on Ubuntu 12.04.1 and
an MinGW-w64 gcc 4.7.2 for Windows. A reduced source test case is attached. The
error does not occur as soon as I use the captured this pointer. Output is as
follows:
$ g++ -std=c++11 ice.cpp -o ice
ice.cpp: In lambda function:
ice.cpp:47:24: internal compiler error: Segmentation fault

minimal test case
I further reduce the test case to a minimum. The ICE only happens if the nested
class is a template.

This happens also with gcc 4.8 HEAD. Further simplifications and removal of
library dependencies:
//-------
void use(int){}
template <typename U>
class C
{
public:
void f()
{
[&]()
{
use(_member);
}();
}
private:
int _member;
};
//-------
After this reduction it looks like a dup of bug 53921 to me.

True, looks like the same bug. My workaround was to define "auto self = this;"
outside the lambda function, but using "this->" bypasses the issue as well.
