#571 ds12c887 causes a crash on exit for x64 (64bit)

I've noticed that when turning on support for ds12c887 RTC support (I used $D500), that when closing out Winvice, it will crash instead of a clean exit. This only seems to happen with the 64bit version of WinVice, 32bit version exits cleanly.
I'll also include a program which can be used to test/use with the RTC to get/display the time, date and day. Bug ticket #467 I noticed on here was asking for something such as this in order to test the RTC.

this one is strange... i could reproduce it first, then changed some stuff in order to track down the bug, and the crash disappeared, cant reproduce it now shrug

could you try with a recent snapshot from pokefinder?

now it happened again, here is a backtrace:

it may be related to switching off/on the rtc at runtime, or changing the base address....

likely related to the RTC being mapped to "internal" I/O space and still registered as a cartridge (see "export" command in monitor). likely related to bug #467
