[fpc-pascal] Self pointer existence

Hi When does the self pointer's value become valid? I need a reference to the object being created inside the object's own create method. The last statement in Create uses self, but that causes program crashes. Is this too early to use self? Is there another way?

Thanks for the resonse Jonas Is it safe to create a dynamic array with setlength() in one thread and free the array using finalize() in another thread? Normally, you should not call finalize() on dynamic arrays. When the last reference to a dynamic array goes out of scope, it is finalised

Re: [fpc-pascal] Sharing dynamic arrays between threads

Calling dispose() on a record with a dynamic array field will free the array (and recursively finalize all its elements) as long as the pointer on which you call it is correctly typed in the source code. The fact that you still get memory leaks after everything you are doing suggests that
