The code can be found here:

But basically I have an array of pointers, that are all assigned a Bullet class using the new operator. However, when one of those Bullet classes tries to write to one of it's variables (like in Bullet::update()), a segfault occurs. And I tried viewing a few variables using which are supposed to be zero-initialized using cout, but I get a bunch of garbage
Class segmentation fault
I can't see anywhere in Bullet.h where you assign the member variable owner. Since it also isn't initialised to null, it means that it is pointing to random data and potentially will crash when you try to deference the pointer.
I can't see anywhere in aggressiveEntity.h where you assign myBullets. Since it also isn't initialised to null, it means that it is pointing to random data and potentially will crash when you try to deference the pointer (which will happen in the update loop).
In aggressiveEntity::shoot, you 'new' an array of bullets but don't keep a reference to the array. I assume you mean to assign temp to myBullets? (Also, you have a potential memory leak here as you don't free up existing memory when create a larger array).

oops I forgot to upload my latest changes to the code<br>
the owner variable isn't there anymore, and I think that only now have I decided to start using an array of pointers to Bullet's scattered around in the heap instead of the Bullet's being laid out sequentially in memory

I added the following code to aggressiveEntity::shoot()
//Copy temp to myBullets
delete[] myBullets;

delete[] myBullets;
I don't see where you initialize myBullets in the constructor.
If you convert to using std::vector instead of rolling your own version of the same thing, does the problem still occur?
As Bregma points out you are not initialising myBullets so calling delete on it will not end well for you.
void shoot(const int cursorX, const int cursorY)
{
//Update timeStep
if (!timeStepUpdatedThisLoop) updateTimeStep();
if (!timeStep) return;
//Calculate mouse position relative to level
int relativeX = mylevel->texture.getW()-cursorX;
int relativeY = mylevel->texture.getH()-cursorY;
//Create a new bullet object in the bullet array
Bullet** temp = new Bullet*[++myBullets_size];
for (int i{}; i<myBullets_size-1; ++i)
{
temp[i]=myBullets[i];
}
temp[myBullets_size-1] = new Bullet(x,y,cursorX,cursorY,*mylevel);
temp[myBullets_size-1]->texture.assign(texture.getCamera());
}
You have a memory leak right there too. 'temp' is just lost.
the owner variable isn't there anymore, and I think that only now have I decided to start using an array of pointers to Bullet's scattered around in the heap instead of the Bullet's being laid out sequentially in memory
You still have this problem that I mentioned with aggressiveEntity.h.
I can't see anywhere in aggressiveEntity.h where you assign myBullets. Since it also isn't initialised to null, it means that it is pointing to random data and potentially will crash when you try to deference the pointer (which will happen in the update loop).
