I have created a DLL with Borland C++ 4.5 which does something 
like this:

<<<

#include<iostream.h>

class A
{
  public:
    void DoException();
};

void A :: DoException()
{
  try {
    throw ( long( 55 ) ); }

  catch ( long x ) {
    cout << "catch " << x << "\n"; }

}

///
// the exported function
///

extern "C" {
  void _export _cdecl Func1();
}


void _export _cdecl Func1()
{
  A a;
  a.DoException();
}

<<<

I have a little C++ test program that just calls the exported 
function Func1() which throws the exception:

<<<

extern "C" {

  void Func1(); }


void main()
{
  Func1();
}

<<<

When I compile the test program with Borland C++ 4.5 the 
program works as expected. 
But when I compile it with MSVC 4.0 the program crashes:
When the function Func1() is called in main() under the 
debugger, I receive an "unhandled exception in 
test.exe(KERNEL32.DLL): Access Violation."

Please help me!!
