why does g++ not warn about division by zero?

[Martin Ettl]

Hi,

i am wondering a bit why g++ (version 4.3.3,Ubunut-Jaunty,32-Bit) does not warn about a divsion by zero. I created a testcase do demonstrate:


#include <iostream>

template <typename T1, typename T2> inline T1 foo (T1 const& a, T2 const& b)
{
	// ....
    return a/b;
}

int main()
{
	std::cout << foo(4.,0) << std::endl; 
	return 0;  
}

I compiled the testprogramm with following command:
g++ -W -Wall -pedantic -o test test.cpp

g++ does not raise a warning!


Best regards 

Ettl Martin
