File Stream Open Problem with g++ 3.3.3 and libstdc++.so.5

Question

Hi
I am facing one problem when I complie and run my code
with the following compiler and standard C++ library :
OS Used : SunOS GUILIN 5.8 Generic_108528-13 sun4u sparc SUNW,UltraAX-i2
Compiler Used : g++ 3.3.3
Standard Library Used : libstdc++.so.5
Problem : I am supposed to create 1000 file streams,
but when I run my program, it creates only 254 file streams,
after that assertion occurs!!!!
OUTPUT :
========
$ echo $SHELL
/usr/bin/sh
$
$ ulimit -n
50000
$
$ ./a.out
i : 253
errno : 24
Assertion failed: in, file main.cpp, line 28
Abort - core dumped
$
========
MY CODE :
==================================================
#include <sys/errno.h>
#include <assert.h>
#include <fstream>
#include <iostream>
#include <string>
extern int errno;
const int MAX_STREAM = 1000;
using namespace std;
int main(int argc, char* argv[])
ifstream in[MAX_STREAM];
string file("boo");
for ( int i=0; i != MAX_STREAM; i++ )
in[i].open(file.c_str());
if ( errno > 0 ) {
cout << "i : " << i << endl;
cout << "errno : " << errno << endl;
} // end of "if ( errno > 0 ) {"
assert(in[i]);
return 0;
===================================================
But, if I compile the exactly same program with the
following compiler and run the executable under the
same environment as above, it is running without
any problem and 1000 file streams are created
smoothly without any assertion.
OS Used : SunOS GUILIN 5.8 Generic_108528-13 sun4u sparc SUNW,UltraAX-i2
Compiler Used : g++ 2.95.3
Standard Library Used : libstdc++.so.2.10.0
Anybody can help me to overcome this problem with
g++ 3.3.3 compiler and libstdc++.so.5 library.

CVS differentiate text and binary files (they are marked as one or the other by using a CVS option when adding the file). If a file is marked as text, cvs will perform line-end conversion if needed.
On Linux, line endings are coded as LF, whereas on Windows they're coded as CRLF. When you copied files from Windows to Linux, you probably did a binary copy, which left the CRLFs intact. When you checked those files into CVS on the Linux server, Linux CVS did not convert the CRLFs into LFs.
The result of this is that if you check the files out on Linux, they will still contain CRLF (which is wrong for Linux). You may verify this by checking out a file on Linux, then opening it using vi -b. The CRs should show as extra ^M's at the end of each line.
If, on the other hand, you check out the file on Windows, a conversion will take place, where all LFs are converted to CRLF. The result of this is that your file will contain CRCRLF at the end of each line.
The best way to fix this is probably to check everything out on the Linux box, remove every CR from every file, then check everything back in again.
