Qt application crashing - Heap errors?

[System123]

Thanks

You are correct, it is my delete[] statements that are causing the errors, but I don't know why because I am quite sure I implemented them correctly. All my Heighmap and GaussKernel structs can only be created using the constructor.

I have reprogrammed the way somethings work, but I am still getting the same problems.

here is the stack trace from Qt Creator

If anyone would like to look at the code e-mail me and I will send the full code to you, I don't want to attach it because it is a current project.

Thanks for the help, it was a stupid problem of me not editing using the correct variable when in the array, so the array index was negative.
