The tools works just fine when built using Tiger and run on Tiger.
Moreover
the same Xcode project file is used (on Tiger and Leopard), and is
using
10.4 SDKs. If I copy the tool from the Tiger system to Leopard, it
crashes
in the same way.
If I attempt to debug the tool in Xcode, it works just fine?!
Of course, "runs just fine" just means "runs without crashing." You've
still got a bug, it just isn't doing anything showy.
A memory error in objc_msgSend almost always means you're attempting
to use an object that has been released prematurely. Look up
NSZombieEnabled, and apply it to your project. It should give you some
clues.
