MEM_BAD_POINTER when calling VI with LVRT adapter

Question

Hi,
I'm using TestStand 2010 and LabVIEW 2010.
One test (sequence) calls VIs that control Agilent 16900A logic analyzer: run and stop (Stop VI is attached for example).
These VIs use ActiveX - LA COM Automation client software.
Everything worked properly, until I switched the LabVIEW adapter from "Development System" to "LabVIEW Run-Time Engine" (in order to make deployment).
When a step that call the logic control VI is executed, I have got the error ”SmartHeap Library - MEM_BAD_POINTER", then "SmartHeap Library - SmartHeap error handler recursively re-entered"- and TestStand is crushed.
Never saw the such problem before.
Any help is appreciated!

Hi Courtney,
This VI works fine in LabVIEW, I even built EXE based on this VI - it works too.
In the meantime I tried to connect with the logic via Visual C++ using the same LA COM Automation client software.
Wrote DLL with functions Run and Stop, created 2 steps in the TS sequence - the both call the DLL Stop function, loaded dynamically and unloaded when step is finished.
The first call is performed, the second call causes the "MEM_BAD_POINTER" error etc.
If the sequence has only one call to the DLL function (e.g. Stop) - I may run it several times successfully.
