Description Isaac.Eckert 2012-12-13 16:20:01 UTC
SIGABRT is missing cause message.  I keep getting a SIGABRT that does not include a cause message above the stacktrace.  Also, the stacktrace is different each time; almost random.  I can only guess at this point what is causing the SIGABRT.

Expected: All SIGABRT messages are supposed to have a cause that is printed to the console above the stacktrace.

Below is my console output in case it helps.  I have many more different kin

=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

In case you don't believe random stacktraces, here is another while performing the exact same tasks as before.  Again, no cause message.

=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

Comment 2 Isaac.Eckert 2012-12-13 16:45:16 UTC
Found an error message on the device log.  Looks like this SIGABRT is being caused by a lack of type 2 trampolines.  Any way to get that written to the debugger?
Comment 3 Rolf Bjarne Kvinge [MSFT] 2012-12-14 04:58:12 UTC
We're working on eliminating the need to say how many trampolines are needed, so this problem will be entirely gone in a future release.

That said you should always check the device log for any messages when you get a crash, in some cases you'll find information there which is not possible to write anywhere else (and it may be iOS writing important information there, not necessarily MonoTouch).
