libFormat + auto-indent + lambda = crash

This seems to happen if Options > Text Editor > Behavior > Enable automatic indentation is enabled.  I do not know if it happens on other platforms/environments at the moment.

Start a new non-Qt C++ project.  I used CMake.

Have some kind of code to work with:

#include <iostream>
#include <functional>

void foo(std::function<void(int,int)>);

int main()
{

}

Now type the following in main:

    foo([](int i, int j){})

Your cursor should be in the {} at this point. Press enter. Crash.
