Description

I used this code in update

for (int i=0;i<1000;i++){
ofFbo dummy;
dummy.allocate(200, 200, GL_RGBA);
}

I can observe that the memory is increasing. Destroy is called and Xcode can not detect this leak.

Research direction

Reproduce the reported loop in update using ofFbo::allocate(200, 200, GL_RGBA), then inspect the allocation and destruction behavior of the temporary ofFbo objects. Done means repeatedly allocating and destroying these objects no longer causes observed memory growth.
