[omniORB] Troubles with wstring

[Giuseppe Naccarato]

Hi,

I defined the following idl:

interface Foo {

   void startFoo(in wstring arg0 );
   void startInt(in long arg0 );

};

Then I implemented a C++ Corba Server and compiled it with VC++ 6.0. 
Here the server:

#include <iostream.h>
#include "Foo.hh"


// FooImpl
class FooImpl : public POA_Foo, public PortableServer::RefCountServantBase
{

public:

   // Constructor
   inline FooImpl() {}
   // Destructor
   virtual ~FooImpl() {}

   // IDL Interface methods
   virtual void startFoo(const CORBA::WChar* msg);
   virtual void startInt(CORBA::Long n);

};

// IDL Interface dummy method implementations


void FooImpl::startFoo(const CORBA::WChar* msg){
   cerr << "::startFoo() msg=" << msg << endl;
}

void FooImpl::startInt(CORBA::Long n){
   cerr << "::startInt() n=" << n << endl;
}


static CORBA::Boolean bindObjectToName(CORBA::ORB_ptr, CORBA::Object_ptr);

int main(int argc, char **argv)
{
   try {

	CORBA::ORB_var orb = CORBA::ORB_init(argc, argv, "omniORB4");
	CORBA::Object_var obj = orb->resolve_initial_references("RootPOA");
	
     PortableServer::POA_var poa = PortableServer::POA::_narrow(obj);
	
     FooImpl* foo = new FooImpl();
	poa->activate_object(foo);
	
     obj = foo->_this();
	
     if( !bindObjectToName(orb, obj) )
       return 1;

	cerr << "FOO_OBJECT is now available!" << endl;
	foo->_remove_ref();
	PortableServer::POAManager_var pman = poa->the_POAManager();
	pman->activate();
	
	cerr << "[1]";
     orb->run();
	cerr << "[2]";
     orb->destroy();
	cerr << "[3]";
   }
   catch(CORBA::SystemException&) {
     cerr << "Caught CORBA::SystemException." << endl;
   }
   catch(CORBA::Exception&) {
     cerr << "Caught CORBA::Exception." << endl;
   }
   catch(omniORB::fatalException& fe) {
     cerr << "Caught omniORB::fatalException:" << endl;
     cerr << "  file: " << fe.file() << endl;
     cerr << "  line: " << fe.line() << endl;
     cerr << "  mesg: " << fe.errmsg() << endl;
   }
   catch(...) {
     cerr << "Caught unknown exception." << endl;
   }
   return 0;
}

etc...


I also developed a Java client using the JDK 1.4 and JavaIDL.

When the client calls the startInt method, everything works fine. 
Instead, if startFoo is called (with a java string as parameter) the 
server properly executes the method but then it crashes showing a 
windows dialog: _BLOCK_TYPE_IS_VALID.

I suppose there's something wrong with the wstring.... but what?

Thanks
