In fact, further investigation shows that commenting out any one of the 18 scraps in the survey makes the error go away; also it works without any scraps commented out at 1:999, 1:999.9, 1:1000.1 and 1:1001. So - it looks like I can work around the problem by either omitting a small part of the survey or by outputting at not-quite 1:1000, but it seems to me that something is wrong here! Duncan.
