Hi,

I have an unmanaged DLL that I have written a managed wrapper around,
however I am getting intermitent crashes where it seems like the heap has
been corrupted. My theory is that a garbage collection has moved something
that I didn't expect to be moved. I have scoured the code and have not seen
any obvious pinnings I have missed. Is there any way to tell what the
garbage collector is moving??

Thanks in advance
Daryn

You could try creating a WeakReference for the object you suspect is
getting garbage collected. At the time you need to access it, check the
WeakReference.IsAlive property to see if it's been GC'd.
