I am having trouble using a binary ofstream with DJGPP. I get different
results depending on how I compile my program.

When I compile the following code fragment with:
  gxx test.cc
The resulting a.exe fails, aborting at the final assertion.

However, if I compile with:
   gxx -O3 test.cc
The resulting a.exe runs correctly and creates the file "out".

Note also that if I do not use the ios::binary switch, it works either
way.

As far as I know I am running the lastest installation of DJGPP.
Am I doing something wrong, or can others reproduce this bug?

Thanks

/*test.cc*/

#include <stdlib.h>
#include <assert.h>
#include <iostream.h>
#include <fstream.h>
#include <iomanip.h>

int main() {
 ofstream os("out", ios::binary);
 assert(os);
 assert(!os.bad());
 os << "hello" << endl;
 assert(!os.bad());
 return(0);
 }
