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 :)
$ g++ -v

Reduced testcase:
const int a = 1;
template<const int& b = a> void f() {
f<>();
}
-- CUT ---
Works with a struct though.
Confirmed, not a regression

------- Comment #5 from reichelt at gcc dot gnu dot org 2009-07-12 22:03 -------
Probably due to the fix in PR35828 the original testcase and the one in comment
#3
now compile. However, if I leave out the two "const" in the testcase from
comment #3, the code is rejected which is wrong IMHO.
