Very Computer

Hi,

System: Solaris 7, Sun C++ 5.0
I have problem with multithreading and streams.
For example,
   // tper.cpp
   #include <fstream>
   using namespace std;
   int main()
   {
     fstream f;
     return 0;
   }

If
   #CC tper.cpp -o tper
I have not problems.

But if I'll compile with -mt
   #CC tper.cpp -mt -o tper
and try to execute tper, I receive

   signal fault in critical section
   signal number: 11, signal code: 1,
   libthread panic: fault in libthread critical
section (PID:12955 LWP 1)
   ...

This problem disappears if I use static ( static
fstream f; )

Have you any idea or suggestion about this
problem ?

Thanks in advance,
Vitaliy

Your sample compiled and executed without error.

Make sure you have up-to-date patches for OS & CC.
