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
