Thread: Segmentation fault

When I debug my program it says this

Code:

Program received signal SIGSEGV, Segmentation fault.
In ntdll!RtlEnumerateGenericTableWithoutSplaying () (C:\Windows\system32\ntdll.dll)

I would probably know how to fix it, but it says the problem is in the system32 folder, and I don't want to do anything in there if I'm not sure what I'm doing.

Could some one help me fix this?

Thanks in advance

Odds are, given that millions of people use ntdll without any trouble and you're the only person having trouble with your code, that the problem is actually in your code and not the system code. It's not impossible that your code is blameless, but I would still look there.

Alright, here's my code (sorry, it's a bit sloppy)
