This code works as expected with the 3.0.2 compiler. >How-To-Repeat: #include <iostream> #include <fstream> using namespace std; main() { long i = 100; ofstream des; des.open("/tmp/des.out.txt"); des << hex << i << endl; des << dec << i << endl; cout << hex << i << endl; cout << dec << i << endl; } Expect this code to print out "64" and then "100". But actually outputs "2.14315e-312" and "100". I have collected information available. >Fix: not known, Need a workaround or patch. >Release-Note: >Audit-Trail: >Unformatted: work correctly.
