More to the point, the cpu can catch this error immediately by looking at the virtual address.

You set up an uint8_t array, add one, two, or three to the array's pointer and then typecast to a short, int, or long and try to access the offending result.) tonyt View Public Profile Find all posts by tonyt #4 11-10-2001 TioTony Bit Pusher Join Date: Oct 2001 Last Activity: 7 November 2016, 7:27 PM EST Location: Log in to post comments Anonymous said on Thu, 04/29/2010 - 00:22 Dear Mr. If it is supported, use the Bug Toolkit (registered customers only) to identify any software bugs that you may be experiencing.
