Summary: ios::app bug on RedHat 7.3 with gcc 3.3
Product: gcc
Version: 3.3
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: c++
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: p_hodigere at yahoo dot com
CC: gcc-bugs at gcc dot gnu dot org
Using ios::app to open a file fails on RH 7.3 when compiled with gcc 3.3. The
same application can open the file in append mode when compiled with gcc 2.96.
Attached is the test aplication.
All the following combinations of open mode's fail:
fp.open("some file", ios::app);
fp.open("some file", ios::in | ios::app);
fp.open("some file", ios::in | ios::out | ios::app);
In order to open the file in append mode, both ios::out and ios::app need to
be used:
fp.open("some file", ios::out | ios::app);
Find below a test application to reproduce this bug.
-Pradeep
#include <iostream.h>
#include <fstream.h>
int main() {
fstream fp;
fp.open("test.txt", ios::app);
if (fp.is_open() ) {
fp << "test\n";
fp.close();
}
else
cout << "Unable to open file";
return 0;
}

------- Additional Comments From reichelt at gcc dot gnu dot org 2003-07-05 20:54 -------
Not a bug.
According to paragraph 27.8.1.3, there are only two valid modes for opening a
file using ios::app, namely
1.) ios::out | ios::app
2.) ios::out | ios::app | ios::binary
Previous versions of gcc just were less picky.
Regards,
Volker
