objective c - Weird memory leak with Blocks and copying in certain way in ARC -

-
the following simple code, under arc, in latest xcode (4.6.2) shows leaks when profiled leaks instrument, in ios simulator, in release build configuration -os optimization: - (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions { (int = 0; < 10; i++) { void (^block)() = ^ { nslog(@"%d", i); }; id x = block; [x copy]; } return yes; } it shows 10 leaked blocks. (it not show leaks optimization turned off; turning off optimization not realistic our app.) strange thing is, looking @ memory management history each of leaked blocks, fine -- each has malloc copy , release; release somehow not deallocate it? is compiler bug (it using default apple llvm compiler)? this seems either bug in compiler or leaks instrument, not sure which. should file bug apple. the same leak happens when shortening code this: int = 0; void (^block)() = ^{

-
i know keeping responsive interface in android heavy work must completed in independent thread. understand how accomplish (by using asyntask..., etc), , not point of question, know. but i've been struggling while simple parallel program. program search lowest integer in array witch length 15000000. i implemented runnable: ... run(){ highestinteger = integers[firstindex]; for(int = firstindex; < secondindex; i++){ if(highestinteger<integers[i]){ highestinteger = integers[i]; } } } ... highest integer in first half of array (in 1 thread) , highest integer in other half of array (in second thread). the program works on computer (as java/not-android program) , mean parallel times shorter (almost half) serial ones. but on android tablet (4 cores) times same , serial ones shorter. i have notice (with debugger) in tablet there several threads running: the main/ui thread (3 cores left) binder 1 thread (2 cores left) b
