    BasicStream.cpp:581 Assertion

    I get the next assertion in a c++ program, what this mean?

    Code:
    icebox: BasicStream.cpp:581: void IceInternal::BasicStream::writeSize(int): Assertion `v >= 0' failed.
    Here is the code that's assert

    Code:
    Oz::MetaService::MetaObjectManagerPrx
Oz::MetaService::MetaServerManagerI::createMetaObject(
	const std::string& type,
	const Oz::Base::StringMap& attributes,
	const Ice::Current& current)
{
	std::cout<<"createMetaObject"<<std::endl;
	MetaObjectManagerPrx metaObjectManagerPx=0;
	try
	{
		MetaObjectPrx metaObjectPx = metaServer->createMetaObject(type,attributes);
		metaObjectManagerPx = internal_getMetaObjectManager(metaObjectPx,current);
		std::cout<<"metaObjectMagerPx: "<<metaObjectManagerPx<<std::endl;
	}
	catch(const Ice::Exception& e)
	{
		std::cout<<e<<std::endl;
	}
	std::cout<<"createMetaObject END"<<std::endl;
	return metaObjectManagerPx;
}

Oz::MetaService::MetaObjectManagerPrx
Oz::MetaService::MetaServerManagerI::internal_getMetaObjectManager(
	const Oz::MetaService::MetaObjectPrx& metaObjectPx,
	const Ice::Current& current)
{
	MetaObjectManagerPrx metaObjectManagerPx = 0;
	std::cout<<"MetaServerManagerI::internal_getMetaObjectManager"<<std::endl;
	
	if(metaObjectPx != 0)
	{
		try
		{
			Ice::Identity metaObjectId = metaObjectPx->getId();
			
			MetaObjectManagerMap::const_iterator it;
			it = metaObjectManagers.find(metaObjectId);
			if(it == metaObjectManagers.end())
			{
				std::cout<<"MetaObjectManager not Exist"<<std::endl;
				Ice::Identity managerId;
				managerId.name = IceUtil::generateUUID();
				managerId.category = id.category;

				MetaObjectManagerPtr metaObjectManagerPt = new MetaObjectManagerI(
					managerId,
					sessionPx,
					sessionId,
					metaObjectPx);
	
				metaObjectManagerPx = MetaObjectManagerPrx::uncheckedCast(
					current.adapter->add(metaObjectManagerPt,managerId));
	
				metaObjectManagers[metaObjectId]=metaObjectManagerPx;
				std::cout<<"MetaObjectManger created OK"<<std::endl;
			}
			else
			{
				metaObjectManagerPx = (*it).second;
				std::cout<<"MetaObjectManager exist"<<std::endl;
			}
		}
		catch(const Ice::Exception& e)
		{
			std::cout<<e<<std::endl;
		}
	}
	std::cout<<"MetaServerManagerI::internal_getMetaObjectManager END"<<std::endl;
	return metaObjectManagerPx;
}
    Program oput
    Code:
    MetaServerManagerI::getMetaObjectManager
MetaServerManagerI::internal_getMetaObjectManager
MetaObjectManager not Exist
MetaObjectManger created OK
MetaServerManagerI::internal_getMetaObjectManager END
icebox: BasicStream.cpp:581: void IceInternal::BasicStream::writeSize(int): Assertion `v >= 0' failed.
[ icegridnode: Activator: detected termination of server `MetaServiceManager'
  signal = SIGABRT ]
    Any ideas what is the trouble?

    thanks in advance

    Hi,

    Could you post the stack trace from when your application asserted?

    Regards,
    Dwayne

    You just run gdb, then use "attach <pid>", with <pid> being the process ID of icebox. Continue execution, and reproduce the crash. Use the "bt" command to get the stack trace. For more information, please refer to the gdb documentation.

    What's the stack trace for the deadlock? And if you see the previous crash, what's the stack trace for this previous crash? Perhaps it would help if you cut&paste your GDB session.

    When i attach gdb to icebox process i only can see this and the service is deadlock, i don't see the previous crash.

    if i type run inside gdb, the program runs with out dead lock and crash occurs again, but when the crash occurs icebox is still runnig in gdb and i need to type Control C to be able of run other command the second ouput show this, but i think the stack that it shows is related to Control C and not to the icebox crash

    Once you have attached to icebox, use "cont" to continue. Then reproduce the crash. Then get the stack trace of the assert.

    According to the stack trace, the problem is with one of the values returned by getAttributes. What is the signature of this operation, what does it return? Can you put print statements into your code to verify that the returned values are correct?
