How can I track which object has already been release:
You can enable zombies, which will mark deallocated objects' memory
with what they used to be, and can also prevent anything from being
actually deallocated ever, but is a useful way to investigate this
kind of problem (if you can reach the problem before you run out of
memory :) )
See NSDebug.h in Foundation.framework for some info on this.
The code is rather simple:
NSArray *vPolyArray = [NSArray arrayWithObjects: ... ];
[vPolyArray release];
You're over-releasing vPolyArray. +arrayWithObjects: returns an
autoreleased instance, and you're also releasing it explicitly, so by
the time NSAutoreleasePool gets around to releasing it, it's already
gone.
