What does segmentation violation mean?

I'm just curious cause my program keeps saying it. I use a lot of pictures, so I'm thinking it's a memory thing. But how do I fix it?

That's a useless post if there ever was one, ecookman...

QFT.

It basically means you're touching memory not allocated to you. Stop that.

Sounds like you are using so much memory that it tries to write over a section where it's not allowed to.

Except that this is Turing, so chances are it's some internal error. There was another thread recently, where loading a faulty .gif file caused segmentation faults.

As with most bugs -- try to isolate where in your program this fault occurs.
