Check the number of image sections in the image synopsis.
If this value is approx 96, it could be that the linker has stopped
performing demand zero compression.
Demand zero compression is the extracting of contiguous, uninialized
writable pages from an image section and placing these pages into a
newly created demand zero section. A demand zero image section contains
uninitialized, writeable pages which do not occupy physical memory
in the image file on disk, but which when accessed during program execution
are allocated memory and initialized to zero by VMS.
