I think you mean "hung" instead of "crashed"? Activity Monitor
doesn't display anything for an ex-process.
Sure it does, at least for a crashed but not yet ex-process. If you
are running your app in the debugger and it crashes it isn't cleaned
up until you click the stop sign in the debugger or otherwise quit the
debugger. Until the process is cleaned up Activity Monitor will
sample it and show you the stacks for all the threads.
IOW, when you are sitting there pulling out your hair looking at the
stack view which should show a backtrace but doesn't that's the time
to fire up Activity Monitor and view your stack trace.
I don't know why Activity Monitor does a better job of displaying the
stacks than gdb does but in the cases where I needed a backtrace and
gdb showed nothing or question marks AM showed the correct stack.
