Memory Fault

[Unregistered]

What are some common causes which could cause this error?

[doubleanti]

you probably just stepped out of bounds [memory wise] in a protected mode environment... i'd say those are the most common...

oh, those... and uninitialized pointers...

[*pointer]

A good habit to get into is initializing your pointers to null immediately upon creating them. An ounce of prevention is worth hours of debugging.
