This is a regression. 4.6.3 works well.

Described bug seems to refer to a set of bugs related to "this" pointer in
lambdas. They can show up as wrong compiler errors or compiler segfaults.

You can use !this->m_barbar intead of !m_barbar as a workaround.
This bug is still present in 4.7.2.
template<typename T>
struct Struct
{
int member;
Struct()
{
[=]{ !this->member; }; // this works
[=]{ !member; }; // internal compiler error: Segmentation fault
}
};
