Exception in deallocate using class vector

[AntonioMG]

Im having this exception when i use the class vector:

vector <int64> p;
dsdriver::EngineAdmin ea;
p= ea.getEngineIds();

And EngineAdmin is:

class DSUTIL_EXPORT EngineAdmin {
public:
static vector<int64> getEngineIds() ;

When i use p=ea.getengineIds(); its throw me an exception in xmemory:

void deallocate(pointer _Ptr, size_type)
		{	// deallocate object at _Ptr, ignore size
		::operator delete(_Ptr);
		}

I have NO IDEA whats is happening, somebody could help me? If you want more info, i would love to give it..

Would it be possible for you to post the code for your class declaration, the function for getEngineIds(), and your main?

I looked at your code and the only thing that I think would be making a problem for you is the fact that you declared the method as static, but you're instantiating it, and then calling the method from the instances, which is legal, but you might try it calling it statically.

dsdriver::EngineAdmin::getEngineIds();

Also, made some REALLY simple code to see if it was the vector class that was causing your problems.

#include <iostream>
#include <vector>

class EngineAdmin {
	public:
		static std::vector<int> getEngineIds();
};

std::vector<int> EngineAdmin::getEngineIds()
{
	std::vector<int> Avector;
	
	Avector.push_back( 14 );
	Avector.push_back( 13 );

	return( Avector );

}

int main()
{
	std::vector<int> p;
	p = EngineAdmin::getEngineIds();

	return( 0 );
}

That works just fine and doesn't cause any errors.

I know debugging is difficult, and it's even more frustrating breaking down your code into bite size chunks and working up from there, but a lot of times that's the only way you can find problems.

Trying the following to see if it works, and then building up from there.

1) See if the code sample that I posted runs properly
2) If it does do the includes that you need for int64 and int64 ONLY and see if it works
3) After that put the class in the dsdriver namespace and see if it still works
4) keep building upon everything, making sure that you keep it simple and work your way up step by step

There are also times when when .net doesn't like to play friendly with stl classes, so you might want to consider that too.

I really appreciate your help, im keeping working on that:

This WORKS:

#include <vector>
#include "stdafx.h"
#include "client/ServiceFactory.h"
#include "client/ServiceInvocationHandler.h"
#include "admin/EngineAdmin.h"
#include "admin/ManagerAdmin.h"
#include "util/UtilFactory.h"
#include "admin/BrokerAdmin.h"
#include "admin/BrokerInfo.h"
#include "admin/EngineDaemonAdmin.h"
#include "admin/ServiceAdmin.h"
#include "driver/DriverManager.h"
#include "admin/Property.h"

using namespace std;
using namespace dsdriver;
 
std::vector<int64> EngineAdmin::getEngineIds()
{
	std::vector<int64> Avector;
 
	Avector.push_back( 14 );
 
	return( Avector );
 
};
 
int main()
{
	while (true) {
	try {
	dsdriver::DriverManager::connect();
	std::vector<int64> p;
	p = dsdriver::EngineAdmin::getEngineIds();
	cout << p.size() << endl;
	} catch (...) {}}
	return( 0 );
}

And this, doesnt work:

#include <vector>
#include "stdafx.h"
#include "client/ServiceFactory.h"
#include "client/ServiceInvocationHandler.h"
#include "admin/EngineAdmin.h"
#include "admin/ManagerAdmin.h"
#include "util/UtilFactory.h"
#include "admin/BrokerAdmin.h"
#include "admin/BrokerInfo.h"
#include "admin/EngineDaemonAdmin.h"
#include "admin/ServiceAdmin.h"
#include "driver/DriverManager.h"
#include "admin/Property.h"

using namespace std;
using namespace dsdriver;
 
int main()
{
	while (true) {
	try {
	dsdriver::DriverManager::connect();
	std::vector<int64> p;
	p = dsdriver::EngineAdmin::getEngineIds();
	cout << p.size() << endl;
	} catch (...) {}}
	return( 0 );
}

[nexocentric]

The difference between the first example, and the second example is this

std::vector<int64> EngineAdmin::getEngineIds()
{
	std::vector<int64> Avector;
 
	Avector.push_back( 14 );
 
	return( Avector );
 
};

is missing.

You can't use a user function without defining it, even if it's prototyped before hand. Without defining the function the computer doesn't know what to do when the function is called.

Just a side note, when you post code please put your code between

tags. It makes it easier to read.
