[omniORB] Heap error after Visual Studio 2010 upgrade

[Peter Danziger]

Hi,

I have just upgraded an application from Visual Studio 2005 to Visual Studio 2010 SP1. The omniOrb (4.1.6) was compiled with Visual Studio 2010, too.
After the upgrade, I have reproducable crashes in Corba calls (server side) within the dispatching of the call.

My interface is:



interface
vfiVerifier

{

   typedef sequence<string>
ArgumentSequence;

   string executeCommand( in long commandId,  in ArgumentSequence args ) raises(vfiException);

};


The generated dispatch function looks like this:



::CORBA::Boolean

_impl_vfiVerifier::_dispatch(omniCallHandle&
_handle)

{

  const char* op = _handle.operation_name();

  if( omni::strMatch(op,
"executeCommand") ) {

    _0RL_cd_00a16d14322384bc_20000000
_call_desc(_0RL_lcfn_00a16d14322384bc_30000000, "executeCommand", 15,
1);

    _handle.upcall(this,_call_desc);

    return 1;

  }


The code crashes in the destructor of the _call_desc object with a heap corruption error. 

Call stack:

     ntdll.dll!77249ea5()     

If I remove the line "_handle.upcall(this,_call_desc);", the code doesn't crash (and of course, doesn't dispatch the call).

I never had any problems with Visual Studio 2005. Does anybody have an idea how to fix this problem?

Regards,
Peter
