On Linux x86_64
g++ --version:
g++ (Debian 20100117-1) 4.5.0 20100117 (experimental) [trunk revision 155979]

Compiling with:
g++ -O2 -g -std=c++0x -c test.cpp

The following program:

#include <vector>
#include <map>
struct Foo {
    Foo() {}

    template<typename Tp>
    Foo(Tp *p) {}
};

void foo() {
    std::map <int, std::vector<Foo>> the_map;

    the_map[1] = std::vector<Foo>();
}

Produces the below error. However, it *doesn't* produce an error if compiled
without the -g switch (nor with -O1 instead of -O2).
