Actually, I solved the error for my situation last night - I just forgot
to write it in as SOLVED.  I had created a temporary pointer, then
assigned the temporary pointer to a variable I was planning to return
from a method, then deleted the temporary pointer.  I'm not used to
using pointers.  I've always heard that you should always delete your
pointers when you're done with them and for some reason I thought the
delete keyword deleted the pointer instead of the memory it was pointing
at...
