This whole thing makes me wonder: is there truly no reliable, simple
method to tell Windows to create a core dump on crash, without writing
custom code for it. I haven't seen one, but I find it amazing if there
isn't. We can't be alone with this.
Search for 'dbghelp.dll' on your average Windows system and you'll be
surprised how many apps use it. Steam (the software distribution system)
does, as does the Adobe Creative Suite on my machine.
If you're running in interactive mode with access to the user's display
you can use Windows error reporting. Services running in isolated user
accounts don't seem to be able to use that. In any case, windows error
reporting only collects *tiny* dumps with barely anything beyond the
stack contents; they're a nightmare to use, and really require psychic
powers and deep knowledge of scary Windows APIs for effective debugging.
