Hi Bruce,

thanks a lot for the feedback.

Loch v13Mar2017 beta works OK, except always crashes if I right-click to view the context menu (Loch v5.3.16is always just fine).

This is probably related to cross-compilation. When I compile on Win32, no such error occurs, but same error with downloaded version also on Win 7. I will try to investigate the problem, but it will definitely take some time.

warning -- error deleting temporary directory -- C:\Users\Bruce\AppData\Local\Temp\th10044

I have no idea about this.

For Therion v13Mar2017 beta version, only loop-closure survex tested: Crashes almost immediately while reading file, complaining about ‘symbol-show point cave-station:fixed’ as per attached log file. I’m guessing this unrelated to the loop closure method used.
./LayoutMapThisCave.thc [54] -- unknown symbol specification -- point cave-station:fixed
writing xtherion file ... done

Same error on my machine, I will try to fix it.

Therion v13Mar2017 beta version crashes (similar to the image above) when there are two or more loops present, unless ‘loop-closure therion’ is explicitly set in therion.ini. Tested on projects with zero, 1, 2 and up to 107 loops. This seems a pretty reliable hypothesis, but I want to test a few more projects with 1, 2 and 3 loops to be sure.

May be, this is related to reading of survex loop closure statistics, which was added recently. I have tried on my dataset with survex loop closure (which is default), but without any crash. Are you able to isolate some small dataset, where this happens to you?

Thanks, S.
