The SSCLI's garbage collector can allocate from more than one chunk of memory. g_lowest_address and g_highest_address represent the lowest and highest addresses that *may* contain garbage collected heaps, and are used to quickly estimate whether a pointer is within the GC heap or not. For example, take a look at GCHeap::IsHeapPointer() in sscli/src/clr/src/vm/gcsmp.cpp. You can see the range-check that the pointer is between g_lowest_address and g_highest_address, and only if it is, IsHeapPointer() calls gcheap::find_segment to determine which (if any) GC heap segment contains the pointer.
