The results are easy enough to predict even without looking at the code.  If your
memory allocations are buggy, you get random memory overlays and corruption,
attempts to access non-mapped physical or virtual memory addresses, and so on.

Basically, all the same sorts of issues beginning C programmers encounter before
they understand pointers.
