With crash debug enabled the agent will now report the windows exception code on crash as well as the address causing the crash and the exact git revision he agent was built from. On 64bit systems it will also print a full backtrace including register contents.
Technical details: Our official builds are built with mingw-w64, so we can't use windows api to resolve debugging symbols in our own binaryi. These frames will only include addresses, while api calls are resolved.
However, the agent is now built with dwarf-2 debugging symbols (outdated but better tool support) and stripped of symbols in a separate build step. With the correct unstripped exe the adresses can still be resolved using addr2line:
addr2line -e check_mk_agent-64.unstripped.exe <address>
