How to debug this?

This is an application that is using an NSTask to launch a command line program, that code is almost a verbatim copy of the Animal.app example from Chapter 24 of Cocoa Programming.

Anyway, here is the crash info:

And in the console:

*** malloc[8368]: error for object 0x6: Pointer being reallocated was not allocated

(hadn't seen this one before, it may help.... But I don't know which object 0x6 is...)
