             Bug #: 56299
           Summary: Dependent lambda expression breaks explicit template
                    instantiation
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ers.trion@gmail.com


The following code produces an internal compiler error:

template<class T>
class Foo
{
    void process(Foo m);    
    void bar()
    {
        [this] { process(Foo()); }();
    }
};

template class Foo<int>;


Output: 

foo.cpp: In lambda function:
foo.cpp:11:24: internal compiler error: in get_expr_operands, at
tree-ssa-operands.c:1035
Please submit a full bug report,
with preprocessed source if appropriate.
