Simplify the problem; you have a "local float array" that "all's
well on main thread", but it crashes when "run in the background".
OK -- NSOperation is a red herring.
You have a multithreading bug related to a simple data type.
So...
How do you initialize the float array? ... from main thread, used
on background thread?
What other synchronization points do you have? ... what other data is
shared?
Show some code?
