Architecture of Process Memory Dump Capture Done Right

Sometimes I get requests to review application memory dump capture design. Of course, such requests usually come only when such designs don’t work or there are problems with loading saved crash dumps. The common blueprint of such architectures is a top level exception handler that use some API do capture and save process memory state. However, such designs forget why separate processed were introduced in the first place: to guard process memory space of different unrelated tasks (for related tasks there are threads). The data of the module (and its thread state) that does process memory capture may also be corrupt. The right design would be to show a message box with an information on how to use external process memory dumper such as Task Manager. If we need an automation then the right thing is to rely on WER features. Let separate processes do their work in separate spaces.
