I'm getting an exception breakpoint which make crash my application in UIApplicationMain. The error message is :
name:<read memory from 0x1b failed (0 of 8 bytes read)> reason:<read memory from 0x23 failed (0 of 8 bytes read)>
How can I debug this kind of error ?
When I deactivate the exception breakpoint, the app works normally.
Thank you

Need to know the reason for this error.
I'm very new to HoloLens development. Therefore please excuse me if this is an amateur question. I'm currently working transmitting hand gestures detections of the HoloLens to an external MQTT broker.
My use-case it, when I detect a hand tap(from HoloLens), I need to send(publish) a message to a subscribed topic in an MQTT broker.
I found this example on GitHub (https://github.com/gpvigano/M2MqttUnity). This publishes the message yet do not receive any messages. I'm getting the following error.

Anyone tried this before repository before or any idea about what this error is?
I've been working on a Linphone custom, it all works fine except that every other call I receive when the app is running on the background ou when the phone is locked, I get this error.
But its like every other call or so...
If anyone could help me =D

I am creating a AVQueuePlayer object by adding AVPlayerItems. All player items points to different audio URL and player should play as soon as it buffers.
As I start the app in simulator, I get very strange issue with memory. The console says
malloc: *** mmap(size=2147483648) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
and stack trace points some where internal in the framework. It juts points at function #0 MP3AudioStream::GeneratePackets(AudioFileStreamContinuation&) ()
I am not able to understand what is the issue.
Even adding breakpoint in malloc_error_break, doesn't giving any info.
Can some one help me in fixing the issue.
Thanks
errno code 12 means out of memory.
Check the size parameter that is passed to malloc - it is invalid. The size value of -1 signed (2147483648 unsigned) explains the out of memory error.
When trying the example on http://msdn.microsoft.com/en-us/library/dd904198(v=XNAGameStudio.40).aspx the program crashes on
Line 69: "player.Play(video);"
error message: "An unhandled exception of type 'System.InvalidOperationException' occurred in Microsoft.Xna.Framework.dll
Additional information: An unexpected error has occurred."
I did not change a single character in the code, but used exactly the files as they came out of the VideoPlayback_4_0.zip folder. (can be directly downloaded from http://msdn.microsoft.com/en-us/library/dd904198(v=XNAGameStudio.40).aspx)
I have read in other forums from people experiencing the same problem, but I could not find a usable solution. Does anybody know what causes the problem and how to fix it?

The codex were the problem. Reinstalling Windows resolved the issue.
