[Bug c++/16383] New: internal compiler error: in generate_element_copy, at tree-sra.c:1466

[larsbj at gullik dot net]

I get an ICE when compiling this with -O1:

#include <boost/signals/signal0.hpp>
#include <boost/bind.hpp>

struct Impl {
        Impl();
        void monitorfile() {}
        boost::signal0<void> timeout;
};

Impl::Impl()
{
        timeout.connect(boost::bind(&Impl::monitorfile, this));
}


If I compile whith -O0 then I don't get the ICE.
