Survex 1.1.8 development snapshot uploaded

[Loeffler, David]

Yet more bugs:

(6) If you open Aven without specifying a survey, you get a curious effect with the menus; they open but don't close again cleanly (the blank space where the viewing area would normally be doesn't redraw), so you get a bizarre effect: http://www.ma.ic.ac.uk/~dl505/snapshot2.png.

(7) Consider the following .svx file:

*begin test

*data normal from to tape compass clino
1	2	1.00	30	-5

*data passage station left right up down
foo	0	0.5	0.25	0.25

*end test

I came up with something like this by accident, changing the station name in the passage data by incompetent use of a search-and-replace command. If you cavern this it runs fine, but if you aven the resulting file, it crashes, failing exactly the same assert as the other bug I reported with the -s switch. Obviously this survey should raise an error, but ideally it should be detected by cavern; presumably the best option is for it to raise a warning saying "Station foo has passage dimensions but is not attached to the centerline".

(8) [Really quite serious, much more so than anything else I've mentioned so far] I'm getting a plague of "Bug in program detected!" errors, reporting "Bad memory access" to the console, whenever I try and print or print preview. This may have something to do with the fact that I don't actually have any printers installed, but aven 1.1.7 happily printed postscript to a file, so why doesn't this one? Now that printps has been axed, this is pretty serious as there's no other sensible way to get stuff onto paper.
