The Enable page heap flag turns on page heap verification, which monitors dynamic heap memory operations, including allocate and free operations, and causes a debugger break when the verifier detects a heap error.

System-wide registry entry, kernel flag, image file registry entry |
This option enables full page heap verification when set for image files and standard page heap verification when set in the system registry or as a kernel flag.
Full page heap verification (for /i) places a zone of reserved virtual memory at the end of each allocation.
Standard page heap verification (for /r or /k) places random patterns at the end of an allocation and examines the patterns when a heap block is freed.
Setting this flag for an image file is the same as typing gflags /p /enable ImageFile /full for the image file at the command line.
