In an attempt to track down some difficulties with crash reproduction, I set up UnhandledExceptionFilterto create mini-dump files as described here: Debug custom filters For unhandled exceptions and Effective mini-copies
Dumps have been successfully captured, but I don’t really like to interpret stack information. In the hope that someone else will experience something similar, I will provide as many details as possible. Sorry if as a result this question is a bit detailed.
Visual Studio provides the following dump summary:
