[Bug c++/37511] New: ice for simple legal C++ code

[dcb314 at hotmail dot com]

I just tried to compile the following C++ code with
most recent snapshot of gcc version 4.4, dated 20080912.

# include <iostream>
# include <math.h>

using namespace std;

int
main()
{
        for (size_t i = 0; i < 16; ++i)
        {
                cout << i << ' ' << sqrt( i) << '\n';
        }
        return 0;
};

The compiler said

feb25.cc:15: internal compiler error: Segmentation fault
