Hi,

Your code has memory corruption. This can happen for many reasons, such as if you forget to initialize a pointer, or if use a pointer after it has been deleted.

Use a debugger to run your program (make sure you build it in Debug mode). It will give you more clues on where the memory corruption occurs.

Also, please add '@' before and after your code to make it easier to read.
