Unhandled win32 exception #87

An unhandled win32 exception is thrown while using Smart Responses with Persistent TCP enabled causing PacketSender.exe to crash.

I am using a Smart Response with the following parameters:
If Packet data equals "05 00" Reply with "06 00" with HEX Encoding

I receive three TCP packets with the content "05 00" on separate connections at 1 second intervals, the sender closes the socket immediately after sending the packet. Packet Sender shows "05 00" being received and "06 00" being sent in the log and opens a Persistent TCP window. After 1 second another Persistent TCP window is opened and Packet Sender may or may not show "05 00" being received and "06 00" being sent. Packet Sender then crashes. The "06 00" that shows as being sent from Packet Sender is never received by the sender of "05 00".

Visual Studio JIT Debugger describes the bug as "An unhandled win32 exception occurred in PacketSender.exe [111132]."

Replicating this process without Smart Responses by manually sending the "06 00" response works fine.

How does it do without Persistent TCP enabled?

When Persistent TCP is not enabled it works fine.
