I've been idly wondering whether it would be possible to get garbage

The Boehm-Demers-Weiser collector (used by GCJ, d2c, &c) seems quite
stable on Mac OS X these days, so hopefully it would just be a matter
of slotting GC_malloc into appropriate places in the ObjC runtime...
Does anyone know where I should start? Override +alloc for NSObject
maybe? Or even lower -- somehow replace NSAllocateObject? Or lower
still -- actually replace the system malloc?
Are there any obvious pitfalls awaiting me here?
I'm afraid Apple beat you to it by using a current gcc:
I'm afraid they didn't :-)
*That* documentation is talking about the GNU Objective-C runtime
(click the "Up" link and it actually even says so). Apple don't use
that... they use a derivative of the NeXT Objective-C runtime.
Kind regards,
Alastair.
