Package: g++-4.4
Version: 4.4.5-8
Severity: normal
When compiling the following simple program:
#include <iostream>
using namespace std;
int main()
{
for( int a = 0, b = 1; a >= 0 && b >= 0 ; ) {
cout << a << ", ";
int sum = a + b;
a = b;
b = sum;
}
}
If I use:
g++-4.4 -Wall -O2 -o fib fib.cc
Then the output doesn't stop when the value of a wraps into negative
territory.
If I use:
g++-4.4 -Wall -O0 -o fib fib.cc
Then it does stop, as expected.
