[Bug c++/43868] New: ICE with -g

[joachim dot reichel at gmx dot de]

"g++ -c code.i" works, "g++ -c -g code.i" gives

tmp/code.i: In instantiation of 'Foo_impl<int (Bar::*)()const>::Helper':
tmp/code.i:19:27:   instantiated from 'void Foo_impl<R
(O::*)()const>::do_something() [with R = int, O = Bar]'
tmp/code.i:34:1:   instantiated from here
tmp/code.i:13:5: internal compiler error: Segmentation fault

This is a regression against g++ 4.4.x.

Replacing Some_type by int works. An empty body for do_something() works as
well.

g++ -v:

Using built-in specs.
