just out of curiosity. NeXTStep or OpenStep? The former is not 
compatible with GNUstep, different API names and many different details, 
so I wonder how you can write the same code.
OpenStep instead is quite compatible.
GNUstep itself doesn't need ARC and you can compile without ARC. Easy, 
just use the GCC runtime and so alloc/release/autorelease will do the 
reference counting. I don't know if you can disable ARC with clang


Furthermore for the opposite problem you can enable zombies 
(NSZombieEnabled env variable), as to trace access to deallocated 
objects. But that is the opposite of what you ask: it keeps everything 
"alive", but useful if you debug manual reference counting, since 
accessing a dead object can be hard to trace sometimes.
