The same config with Linux (4G phys + 2G swap):

IDL> memtest
current block size = 2146435072
Memory block # 1: 2047 Mb (total: 2047 Mb)
Memory block # 2: 2047 Mb (total: 4094 Mb)
Memory block # 3: 532 Mb (total: 530 Mb)
Memory block # 4: 63 Mb (total: 593 Mb)

and after changing ULONG to ULONG64 in memtest :-)

IDL> memtest
current block size = 2146435072
Memory block # 1: 2047 Mb (total: 2047 Mb)
Memory block # 2: 2047 Mb (total: 4094 Mb)
Memory block # 3: 547 Mb (total: 4641 Mb)
Memory block # 4: 63 Mb (total: 4704 Mb)
