objective c - iOS app crash only if run from instrument (Automation) -



app not crash on device. no leaks no memory warning. living happily. doing ui testing instrument(automation). boom boom. app crashes after using 8 min. looping around 30 times. , keep crashing after different durations @ same step. again no leaks no memory warning. again not crash on device(without instrument) doesn't matter how long use app.

+ every times crashes after pop specific viewcontroller. , view controller loaded stuffs (image view, playing , recording audio, take photo album , camera) here device log.

any kind of highly appreciated.

exc_bad_access means sending objective c message invalid memory address. happens because object using has been deallocated.

use nszombieenabled more information. start commenting out stuff. it's memory issue, find offending line of code.

assembly - 8086 TASM: Illegal Indexing Mode -

this question has answer here: illegal use of register in indirect addressing 1 answer i writing 8086 assembly program needs compile through tasm v3.1. running error can not seem fix. my data segment has following set purposes of keyboard input: parao label byte maxo db 5 acto db ? datao db 5 dup('$') what trying first character entered, first byte of datao: lea dx, datao mov bl, [dx] however, when attempt compile, error: **error** h5.asm(152) illegal indexing mode line 152 "mov bl, [dx]" any appreciated. if matters, running tasm through dosbox (my laptop running 64-bit win7) google hasn't come helpful answers. can post entirety of code if necessary. pretty sure reason can't use dx register pointer. try instead using [si], [di] or [bx]: lea bx, data0 mov al, [bx]
