It can be used to detect when you:

• access memory should shouldn’t (overrun/underun allocated blocks),
• use undefined values in such a way that your program depends on the results,
• overlap source and destination pointer in memcpy and related functions, and
• free memory incorrectly (don’t free, double free, free with wrong function).

It is highly recommended that you join the webinar a few minutes early to ensure you get your sound option sorted out before the meeting starts.
