Source file + ii + s

Hi,

Please see in attached file the source triggering an internal error in gcc.

The source file is compiled like this:

$> g++ -std=c++11 -W -Wall -Wextra test.cpp 
test.cpp: In instantiation of âstruct test<dummy>::__lambda0â:
test.cpp:5:8:   required from here
test.cpp:8:20: internal compiler error: in tsubst_copy, at cp/pt.c:12116
         { "test", [this]{} }

The bug is triggered when `this` is captured from a template class and the
lambda is assigned directly from the class definition.

The platform tested is an ubuntu 13.10 with default shipped compiler:

$gcc -v
Using built-in specs.

Thread model: posix
gcc version 4.8.1 (Ubuntu/Linaro 4.8.1-10ubuntu8) 

The bug is still present in gcc4.9 (tested via: http://gcc.godbolt.org/).
I joined the *i files even if I doubt that they'll be helpful in this
particular bug.
