You can set up the "unexported symbols" list in Xcode to prevent the OS from calling into your new and delete functions. We've needed to do this in our code to work around various weird issues.
You should still file bugs on the OS for mixing up new[] and delete, they should know better! ;)
Sam,
Overriding the global new and delete operators I'm afraid I've seen
lots of situations like this --although in Tiger (haven't received
Leopard yet).
The mismatch between new[] and delete seems indeed to occur quite
often in the system libraries, but obviously I wouldn't know where...
Sorry,
Dario
