// A normal minidump contains just the information

//
// A minidump with data segments includes all of the data
// sections from loaded modules in order to capture
// global variable contents.  This can make the dump much
// larger if many modules have global data.
//
// A minidump with full memory includes all of the accessible
// memory in the process and can be very large.  A minidump
// with full memory always has the raw memory data at the end
// of the dump so that the initial structures in the dump can
// be mapped directly without having to include the raw
// memory information.
//
// Stack and backing store memory can be filtered to remove
// data unnecessary for stack walking.  This can improve
// compression of stacks and also deletes data that may
// be private and should not be stored in a dump.
// Memory can also be scanned to see what modules are
// referenced by stack and backing store memory to allow
// omission of other modules to reduce dump size.
// In either of these modes the ModuleReferencedByMemory flag
// is set for all modules referenced before the base
// module callbacks occur.
//
// On some operating systems a list of modules that were
// recently unloaded is kept in addition to the currently
// loaded module list.  This information can be saved in
// the dump if desired.
//
// Stack and backing store memory can be scanned for referenced
// pages in order to pick up data referenced by locals or other
// stack memory.  This can increase the size of a dump significantly.
//
// Module paths may contain undesired information such as user names
// or other important directory names so they can be stripped.  This
// option reduces the ability to locate the proper image later
// and should only be used in certain situations.
//
// Complete operating system per-process and per-thread information can
// be gathered and stored in the dump.
//
// The virtual address space can be scanned for various types
// of memory to be included in the dump.
//
// Code which is concerned with potentially private information
// getting into the minidump can set a flag that automatically
// modifies all existing and future flags to avoid placing
// unnecessary data in the dump.  Basic data, such as stack
// information, will still be included but optional data, such
