    copied!<p>We recently tried compiling our MonoTouch application for iOS6, and it invariably crashes about 5 seconds after pressing play in the main menu.</p> <p>Here's the stack trace:</p> <pre><code>Stacktrace: at MonoTouch.ObjCRuntime.Runtime.ConstructNSObject (intptr,intptr) [0x00007] in /Developer/MonoTouch/Source/monotouch/src/ObjCRuntime/Runtime.cs:208 at MonoTouch.ObjCRuntime.Runtime.GetNSObject (intptr) [0x0001f] in /Developer/MonoTouch/Source/monotouch/src/ObjCRuntime/Runtime.cs:259 at MonoTouch.ObjCRuntime.Runtime.GetNSObjectWrapped (intptr) [0x00000] in /Developer/MonoTouch/Source/monotouch/src/ObjCRuntime/Runtime.cs:276 at (wrapper native-to-managed) MonoTouch.ObjCRuntime.Runtime.GetNSObjectWrapped (intptr) &lt;0xffffffff&gt; at MonoTouch.UIKit.UIApplication.Main (string[],string,string) [0x0004c] in /Developer/MonoTouch/Source/monotouch/src/UIKit/UIApplication.cs:38 at Resistor5.Program.Main (string[]) [0x00000] in /Users/nullcandy/Projects/Resistor5/Resistor5_iOS/AppDelegate.cs:22 at (wrapper runtime-invoke) object.runtime_invoke_dynamic (intptr,intptr,intptr,intptr) &lt;0xffffffff&gt; Native stacktrace: 0 Resistor5_iOS 0x011bf7b4 mono_handle_native_sigsegv + 280 1 Resistor5_iOS 0x011a9380 mono_sigsegv_signal_handler + 268 2 libsystem_c.dylib 0x31e17e93 _sigtramp + 42 3 ??? 0x00000000 0x0 + 0 4 Resistor5_iOS 0x0126191c single_arg_user_copy_or_mark + 28 5 Resistor5_iOS 0x0128e4cc mark_tls_slots + 160 6 Resistor5_iOS 0x012650f4 scan_from_registered_roots + 412 7 Resistor5_iOS 0x01271c34 major_collection + 3040 8 Resistor5_iOS 0x01272c98 minor_collect_or_expand_inner + 88 9 Resistor5_iOS 0x012733a0 mono_gc_alloc_obj_nolock + 1336 10 Resistor5_iOS 0x01262db0 mono_gc_alloc_vector + 136 11 Resistor5_iOS 0x01249cf4 mono_array_new_specific + 132 12 Resistor5_iOS 0x0108abb4 wrapper_managed_to_native_object___icall_wrapper_mono_array_new_specific_intptr_int + 68 13 Resistor5_iOS 0x00088090 MonoTouch_ObjCRuntime_Runtime_GetNSObject_intptr + 144 14 Resistor5_iOS 0x00088110 MonoTouch_ObjCRuntime_Runtime_GetNSObjectWrapped_intptr + 28 15 Resistor5_iOS 0x000b8620 wrapper_native_to_managed_MonoTouch_ObjCRuntime_Runtime_GetNSObjectWrapped_intptr + 64 16 Resistor5_iOS 0x012bd634 get_managed_object_for_ptr_fast + 108 17 Resistor5_iOS 0x011a19f4 native_to_managed_trampoline_MonoTouch_UIKit_UIAccelerometer__UIAccelerometerDelegate_DidAccelerate + 324 18 UIKit 0x35f16717 &lt;redacted&gt; + 222 19 UIKit 0x35ca7359 &lt;redacted&gt; + 2820 20 UIKit 0x35ca66d5 &lt;redacted&gt; + 72 21 UIKit 0x35ca6123 &lt;redacted&gt; + 6154 22 GraphicsServices 0x33f395a3 &lt;redacted&gt; + 590 23 GraphicsServices 0x33f391d3 &lt;redacted&gt; + 34 24 CoreFoundation 0x36311173 &lt;redacted&gt; + 34 25 CoreFoundation 0x36311117 &lt;redacted&gt; + 138 26 CoreFoundation 0x3630ff99 &lt;redacted&gt; + 1384 27 CoreFoundation 0x36282ebd CFRunLoopRunSpecific + 356 28 CoreFoundation 0x36282d49 CFRunLoopRunInMode + 104 29 GraphicsServices 0x33f382eb GSEventRunModal + 74 30 UIKit 0x35cfa301 UIApplicationMain + 1120 31 Resistor5_iOS 0x000b769c wrapper_managed_to_native_MonoTouch_UIKit_UIApplication_UIApplicationMain_int_string___intptr_intptr + 240 32 Resistor5_iOS 0x0094d158 Resistor5_Program_Main_string__ + 152 33 Resistor5_iOS 0x01085ce0 wrapper_runtime_invoke_object_runtime_invoke_dynamic_intptr_intptr_intptr_intptr + 200 34 Resistor5_iOS 0x011ab3dc mono_jit_runtime_invoke + 1644 35 Resistor5_iOS 0x0124aa8c mono_runtime_invoke + 128 36 Resistor5_iOS 0x0124ec84 mono_runtime_exec_main + 436 37 Resistor5_iOS 0x0124f044 mono_runtime_run_main + 756 38 Resistor5_iOS 0x011aff14 mono_jit_exec + 140 39 Resistor5_iOS 0x012b7f88 main + 2028 40 Resistor5_iOS 0x000020c4 start + 52 ================================================================= Got a SIGSEGV while executing native code.

Any ideas?</p> <p>P.S. Although the accelerometer is mentioned in the stacktrace, we're not using the accelerometer at any point in the code.</p>
