[omniORB] Problems with String_var

[jjeschin@phoenixcontact.com]

I am not familiar with CORBA and try to write my first server application under
WinNT (VC++6.0). I try to pass a string from the client to the server.
Client Code:
  ...
  CORBA::String_var src = (const char*)"/IP=149.208.19.219";
  CORBA::Long hInst;

  ret = IPFBref->RegisterIPTime(hInst, src);
  ...

Server Code:
HRESULT IPFBORBServer_i::RegisterIPTime(CORBA::Long& hFBInst, const char*
strPartner)
{
    printf("RegisterIPTime()\n");
    hFBInst = 0;
    return 0;
}

When the string variable on the server side goes out of scope and the delete
operator is called I get always a debug assertion:
"_BLOCK_TYPE_IS_VALID(pHead->nBlockUse)".
What's my mistake?
