Purify is a debugging tool that is invoked when you compile your program. Purify adds code that detects when a memory error is going to occur and gives you feedback as to where and why. Purify will detect the following errors (plus a few more):
1. Reading or writing beyond the bounds of an array.
2. Reading or writing freed memory.
3. Reading and using uninitialized memory.
4. Reading or writing through null pointers.
5. Reading or writing beyond the end of the call stack.
6. Having memory leaks.

I'm getting a lot of UMR errors that I don't think my program is causing. We have to turn in a program that doesn't have any Purify errors. How do I get around these?
