Description Przemysław Raciborski 2015-10-11 07:40:45 UTC
Xamarin.Android 6.0 cycle 6, Windows - Visual Studio 2013 / 2015 Debugger very often crash, output log:  * Assertion at /Users/builder/data/lanes/2098/f94dc5b2/source/mono/mono/mini/debugger-agent.c:2587, condition `res' not met [libc] Fatal signal 6 (SIGABRT), code -6 in tid 31229 (IntentService[n) I can not submit reproduction sample. I would have to submit whole application - which I can not do. I'm also not sure what it is caused by - but crashes often occur on Activity where I use Google maps ( google maps v3 ). I am not the only who has such problems, this bug is mentioned by several people on Xamarin Forums - https://forums.xamarin.com/discussion/52444/alpha-release-xamarin-android-6-0-cycle-6-feature-release

I have checked this issue with the mono-android-6.0.0-16. This issue is working fine on Mac XS. I am not seeing any crashes while switching video tab. Here is the screencast for the same: http://www.screencast.com/t/4PFJtXli9Au. I will verify this issue once its fixed on Windows also as we are getting the same crashes on Windows VS and XS. Thanks!

There is now an XVS build which also contains this fin in xamarinvs/cycle6/2ddfb33.
Comment 6 Peter Collins 2015-10-22 15:14:26 UTC
The last comment was incorrect, however we've since tested and confirmed this fix against a cycle6-based pr build of XA and XVS.
