Regarding Deleteing pointer!!!!!

Hi Friends,

Can anyone tell me I am getting an error like this....

Code:

Passing '*this->m_ptr_ptr' as parameter after its value was freed. Object '*this->m_ptr_ptr'  was used at line 184 after being freed by passing argument 1 to function 'delete' at line 173

Here is the code snippet for your reference...

Code:

int *m_ptr_ptr = new com::att::ib::Core_V1_0::NVPair

                .......
                .......
                .......

void
com::att::ib::Core_V1_0::IT_Gen_NVPairStreamable::replace_nonshareable_arg(
    CORBA::IT_InStream_ptr is,
    unsigned long _direction
)
{
    if (*m_ptr_ptr != 0)
    {
        if (m_own_value|| _direction == CORBA::ARG_OUT)
        {
            delete *m_ptr_ptr;
        }
        if (_direction != CORBA::ARG_INOUT)
        {
            *m_ptr_ptr = 0;
        }
        if (_direction == CORBA::ARG_IN)
        {
            m_own_value = IT_TRUE;
        }
    }
    read(is);
}

Please give me the solutions..

Thanks in advance!!!!!

I believe your problem is that you have deleted what the pointer refers to, but when you delete it you haven't removed the pointer's reference to that address. It is still pointing to that address. So set it to NULL.
