Hello everyone!

Here we go again.. writing a solution to a problem which supposedly works on my PC but delivers runtime error on the codeforces server.

The submission I'm talking about is this: 19567131. I've been reading about suffix trees and trying to solve a simple problem. The solution is pretty lengthy, but... Does anyone know what error code 255 is? I also tried custom tests and occasionally I get error code -1073741819. I compile under gcc 5.1.0 — the same as codeforces I think, using c++11. I tried using flags "-std=c++11 -Wextra -pedantic -Wall -O2" but didn't get anything interesting. I've been playing around with this for quite a while now, but I can't seem to get it to work.

I'd be grateful for any help anyone can provide!
