            Bug ID: 62272
           Summary: Gimplify throws error on method call from inside
                    nested lambdas
           Product: gcc
           Version: 4.9.1
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: aaron.plavnick at spottradingllc dot com

Here is a minimal code sample, the bug exists in 4.7.3, 4.8.2, and 4.9.1. I
compiled with -std=c++11

--------------------------------------------

template< typename T >
class B
{
    public:
        void Foo() {}

        void Bar()
        {
            [&]()
            {
                [&]() { Foo(); }();
            }();
        }
};

int main( int argc, char** argv )
{
    B<int> b;
    b.Bar();
    return 0;
}

----------------------

The compiler returns: 

main.cpp: In lambda function:
main.cpp:11:34: internal compiler error: in gimplify_var_or_parm_decl, at
gimplify.c:1741
                 [&]() { Foo(); }();
