Solving corrupt dynamic memory problem

[pblase]

Using LabWindows/CVI 2010, Windows XP. I have a data acquisition program that uses a rather large number of dynamically allocated arrays as buffers. The buffers are used to hold data from DAQmx and are passed and copied to a number of thread-safe queues and other routines. In certain circumstances, when I free one buffer I get a "dynamic memory is corrupt" error, which probably means - from reading the other posts on this topic on this forum - that some buffer was written past its end and corrupted the dynamic memory linked list. Is there any good way to determine exactly <i>which</i> buffer was corrupted? I don't believe that it was the one that I get the error on, it was probably the previous or next one in the chain. I can see the memory chain in the resource window, but I'm not sure how to interpret it.

Hi pblase, 

Here is an KnowledgeBase article that was written for LabWindows\CVI 6.0 but it still has some valid suggestions for debugging in LabWindows\CVI 2010:

There are three valid suggestions to debug from this article.  The only one that does not work still is the Run » Dynamic Memory feature.
