What is: Bad_dump!missing_teb (Windows Phone Dev Center Crash Log)

Question

The following 2 crashes are being reported as our WP 8.1 app's highest occurance crashes based on Window's developer center's crash logs.

Any clue what they mean or how to debug them? I suspect 'out of memory' but would like to confirm.

First:

bad_dump!missing_teb BAD_DUMP_MISSING_MEMORY_MISSING_CLR_METADATA_bad_dump!missing_teb

Second:

bad_dump!missing_teb BAD_DUMP_MISSING_MEMORY_NULL_CLASS_PTR_READ_ZEROED_STACK_MISSING_CLR_METADATA_bad_dump!missing_teb

Answer 1

I've been told by a Microsoft Technical rep that it is a bad dump and you can not retrieve any additional information on it.

He pointed me to the following: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/d74cc413-3c4b-4a92-9c42-058bc41f503f/wp81-cant-identify-the-reason-for-crash-baddumpmissingteb?forum=winappswithcsharp
