Can't load surf data in Windows 8

[Nick Draper]

Hello Mantid team,

Max Skoda and myself are presently running the neutron training course. We are teaching them some basic mantid .

However some of the students have windows 8 machines. We can install the 64bit mantid 3.1.1 version and it runs ok. However it crashes out every time we attempt to load surf data . This only occurs on the windows 8 machines. We have not tested it on other data sets form other machines choosing to pair people up and get on with the course.

We have tried earlier versions of mantid and running everything in compatibility mode with no luck.

This is something we will have to fix as users will start arriving with windows 8 machines more and more as time goes by.

Please contact me if you require any more info.

Cheers

Christy

This appears to be a problem with monitor2, and is occurring as part of the trianglutaion in opencascade.

If you remove the cylinder part of the shape then the problem goes away.

This is not the best fix possible, but the error is a memory violation in the heart of opencascade and in uncatchable.

I have created ticket #9148 to look into a replacement for opencascade.

To test:

1. Ask me for 5 mins on my laptop
2. Load up a surf dataset - if it doesn't crash then all is well.
