the bad point or not point to local heap?

I do something in c# language, but I also want to use
the DLL which writed in c++.So I used the trusteeship as
the c# help file teached us. But unfortunately I failed. I
look for the reason. First, I found the DLL could work
well in vc6.0, but if I let c# use the DLL, when the time
to release the memory in c++, it went to wrong. It told me
that the pointer of the memory to release is bad or it
didn't point to local heap. I am so puzzled. Could someone
give me any suggest?
The DLL I used is snmp++ which given from HP,and which
I do is just to use 'set' in C# language, the problem come
from ~vb() in snmp++.
I want to know whether this problem is come from c#
language trusteeship?
Please help me.
