>Description:
I open a file to write, read and write again.
when the program finish I check the files I created and the out put is not what its suppose to be.
only the first write works!
I compiled the same program with g++ 2.96 and I got the out put I wanted. so I think this could be some kind of bug.
in the How-To-Repeat seccion I included an example code.
it creates a file named infile.txt but if I compile it with g++3 I get a wrong output in the file.
>How-To-Repeat:
#include <fstream>
#include <iostream>
int main(void)
{
char a;
std::fstream ipo("infile.txt", std::ios::ate | std::ios::out);
if (!ipo)
{
std::cout << "File does not exist.";
return -1;
}
ipo.put('.');
a = ipo.get();
ipo.put('A');
ipo.close();
return 1;
}
