Hi,
The _snmp_sess_asynch_send() function deallocates the PDU allocated by the
snmp_create_pdu call.
In the context of Windows, there is a major drawback to this:
1. snmp_create_pdu does not allocate memory for PDU enterprise, and
community; the user application has to allocate them separately.
2. Hence, the PDU enterprise and community strings are allocated in the
local heap of the user application.
3. The _snmp_sess_asynch_send() function deallocates the PDU after it is
sent (a call to snmp_free).
4. snmp_free also deallocates the enterprise and community strings. These
however are not in the local heap of the loaded DLL.
5. This causes Windows to throw a user breakpoint (while debugging), and
causes the application to freeze (while running in release mode).
In my application, I have fixed this problem, but I thought I should let you
guys know of the issue.
