Thanks for the test. This report is not much encouraging considering that it shows the test confuses pointer calculations and pointer dereferences. Indeed, I've checked them all and they're all the byproduct of calling LIST_ELEM to retrieve a list element from the list's pointer, which is done by subtracting an offset from this pointer. There is absolutely no memory access done there. Thus I guess this rules out any hope to use this in automated tests :-) Willy
