I am using sortArrayUsingFunction: context: to sort a fairly large

a halt. No message, no nothing. It just stops.
Do you mean the process exits? Or hangs?
If it exits, it's probably an abort( ) call somewhere — run it in the
debugger and see if it catches it. If not, set symbolic breakpoints on
exit( ) and abort( ).
If it hangs, sample it, using the 'sample' command or Activity
Monitor. Or run it in the debugger and push the pause button.
