With the following piece of code:

==============================
struct integer
{
    int i;
};

struct foo1
{
    double d;
    int i;
};

struct foo2
{
    double d;
    integer i;
};

int main(int argc, char **argv)
{
    int i1 = 0;
    integer i2{0};

    foo1 f1{3.2, i1}; //ok
    new foo1{3.2, i1}; //ok

    foo2 f2{3.2, i2}; //ok
    new foo2{3.2, i2}; //error, why?

    return 0;
}
==============================

GCC 4.4 svn (4.4.0 20081005) can't compile "new foo2{...}" line:

==============================
$ g++ -std=c++0x main.cpp
main.cpp: In function 'int main(int, char**)':
main.cpp:53: error: could not convert '{3.20000000000000017763568394002504646778106689453e+0, i2}' to 'foo2'
==============================

though the other lines are OK.

I didn't see anything about a difference between the two forms in the standard, so I guess it is a GCC bug.
