I've got lots of crash like this below: Thread : Crashed: com.apple.main-thread 0 ImageIO 0x30c808fc vec_ycc_bgrx_convert + 427 1 ??? 0x27d440d0 2 ImageIO 0x30c80707 sep_upsample + 170 3 ImageIO 0x30cc3dfb process_data_simple_main + 94 4 ImageIO 0x30c7f5df _cg_jpeg_read_scanlines + 82 5 ImageIO 0x30c7d6f7 copyImageBlockSetJPEG + 3262 6 ImageIO 0x30c66779 ImageProviderCopyImageBlockSetCallback + 528 7 CoreGraphics 0x2ffa347d CGImageProviderCopyImageBlockSetWithOptions + 136 8 QuartzCore 0x323eef59 CA::Render::create_image(CGImage*, CGColorSpace*, unsigned int) + 680 9 QuartzCore 0x323ee409 CA::Render::copy_image(CGImage*, CGColorSpace*, unsigned int, double) + 292 10 QuartzCore 0x323c766d -[CALayer(CALayerPrivate) _copyRenderLayer:layerFlags:commitFlags:] + 484 11 QuartzCore 0x323c7481 CA::Layer::copy_render_layer(CA::Transaction*, unsigned int, unsigned int*) + 32 12 QuartzCore 0x323c741b CA::Context::commit_layer(CA::Layer*, unsigned int, unsigned int, void*) + 94 13 QuartzCore 0x323c43fb CA::Layer::commit_if_needed(CA::Transaction*, void (*)(CA::Layer*, unsigned int, unsigned int, void*), void*) + 314 14 QuartzCore 0x323c4399 CA::Layer::commit_if_needed(CA::Transaction*, void (*)(CA::Layer*, unsigned int, unsigned int, void*), void*) + 216 15 QuartzCore 0x323c4399 CA::Layer::commit_if_needed(CA::Transaction*, void (*)(CA::Layer*, unsigned int, unsigned int, void*), void*) + 216 16 QuartzCore 0x323c4399 CA::Layer::commit_if_needed(CA::Transaction*, void (*)(CA::Layer*, unsigned int, unsigned int, void*), void*) + 216 17 QuartzCore 0x323c4399 CA::Layer::commit_if_needed(CA::Transaction*, void (*)(CA::Layer*, unsigned int, unsigned int, void*), void*) + 216 18 QuartzCore 0x323c4399 CA::Layer::commit_if_needed(CA::Transaction*, void (*)(CA::Layer*, unsigned int, unsigned int, void*), void*) + 216 19 QuartzCore 0x323c4399 CA::Layer::commit_if_needed(CA::Transaction*, void (*)(CA::Layer*, unsigned int, unsigned int, void*), void*) + 216 20 QuartzCore 0x323c4399 CA::Layer::commit_if_needed(CA::Transaction*, void (*)(CA::Layer*, unsigned int, unsigned int, void*), void*) + 216 21 QuartzCore 0x323c4399 CA::Layer::commit_if_needed(CA::Transaction*, void (*)(CA::Layer*, unsigned int, unsigned int, void*), void*) + 216 22 QuartzCore 0x323c2719 CA::Context::commit_transaction(CA::Transaction*) + 1048 23 QuartzCore 0x323c21f7 CA::Transaction::commit() + 314 24 UIKit 0x329ac2c9 _UIWindowUpdateVisibleContextOrder + 208 25 UIKit 0x329ac15d +[UIWindow _prepareWindowsPassingTestForAppResume:] + 16 26 UIKit 0x32951539 -[UIApplication _handleApplicationResumeEvent:] + 76 27 UIKit 0x32750613 -[UIApplication handleEvent:withNewEvent:] + 1882 28 UIKit 0x3274fdf9 -[UIApplication sendEvent:] + 72 29 UIKit 0x327b4405 _UIApplicationHandleEvent + 616 30 GraphicsServices 0x34dbdb55 _PurpleEventCallback + 608 31 GraphicsServices 0x34dbd73f PurpleEventCallback + 34 32 CoreFoundation 0x2fee6847 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE1_PERFORM_FUNCTION__ + 34 33 CoreFoundation 0x2fee67e3 __CFRunLoopDoSource1 + 346 34 CoreFoundation 0x2fee4faf __CFRunLoopRun + 1406 35 CoreFoundation 0x2fe4f769 CFRunLoopRunSpecific + 524 36 CoreFoundation 0x2fe4f54b CFRunLoopRunInMode + 106 37 GraphicsServices 0x34dbc6d3 GSEventRunModal + 138 38 UIKit 0x327ae891 UIApplicationMain + 1136 39 myApp 0x001cedd9 main (main.m:26)
I can know only that some jpeg files are wrong to render on screen, but how can I know which one or where the crash happed?
The common backtrace is from CA::Layer::commit_if_needed to vec_ycc_bgrx_convert. I've got lots of crash logs from user, but I can't reproduce it, anyone can help?
