[Bug c++/37766] New: [C++0x] ICE with function's default reference template parameter

["florian dot goujeon at wanadoo dot fr" <gcc-bugzilla@gcc.gnu.org>]

The following piece of code:

=====================================================
#include <string>

const std::string space(" ");

template<const std::string& Str = space>
void f()
{
}

int main()
{
    f<>();
}
=====================================================


leads to a compiler internal error:
=====================================================
$ g++ -std=c++0x main.cpp space.cpp
main.cpp: In function 'int main()':
main.cpp:3: internal compiler error: Segmentation fault
=====================================================


This bug occurs with any reference template parameter (i.e. not only
std::string&).



I hope my reports are helpful :)
