Before you get any advice on your problem, I must warn you about some problems that may cause some experts to avoid communicating with you.

I noticed that you got a number of recommendations to avoid allocating memory in one executable module and deallocating in another one. You asked 5 (five) very similar questions in a row. You seem to systematically ignore the recommendations. More than that, I offered you a stricter rule for memory allocation and deallocation.

Any person would be interesting in helping you if this effort produces some result. Not only you not following the recommendations, you do not express any concern about it. If you doubt that the recommendation is valid or useful, you should express you doubt by commenting the solution. Instead of doing this, you simply ignore it and simply repeat the same wrong idea in another question in a slightly different form.

You should consider my recommendations in the second paragraph above (which simply repeats previous recommendations you already got before) as a solution. Without accepting it and changing your approach to memory allocation your further question will not have any sense. If you need deeper explanations of it or don't understand the answers — this is a different story; but in this case you should explain your concerns.

Please understand that anyone expect honest and responsible behavior from a person receiving help, otherwise there are no reasons or motives for help.

If you disagree with anything I say, you should explain why. But first of all you should explain: what would be the reasons for anyone to help you.

Thank you for your understanding,

—SA
