So I'm loading some images from files which I saved in the app's document directory and upon completion, I update a dictionary which holds all the images for my tableview. So far so good, everything's working just fine.
But now I've stumbled upon a really peculiar crash. Sometimes when updating the dictionary the app crashes, giving me the error message: "Heap corruption detected, free list is damaged at ...".
I've added a symbolic breakpoint at malloc_error_break and turned on the Address Sanitizer the Undefined Behaviour Sanitizer and Zombie Objects as advised in this post: iOS error : Heap corruption detected, free list is damaged and Incorrect guard value: 0
Now I'm getting the following error message, which doesn't really help me either:

I have no clue as to what could've caused that crash, hopefully someone can help me out here!
