OCC crashes on a system of mine when using TopAbs_EDGE or TopAbs_FACE with AISContext->MoveTo. Visual studio says:
Unhandled Exception: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
You can see a screenshot of the detail-dialog at http://picpaste.de/details-KrG44qp7.png
I can reproduce it with the viewer3d-sample too:
* Run texture example
* activate edges or faces selection mode (vertices and neutral point are working)
* move mouse over the bottle
Because it's working on other systems I reinstalled Windows (7 Professional SP1 64bit), ran updates, installed drivers, visual studio and opencascade again, but the error stays the same. To eliminate the graphics card as the source of the problem I deactivated my AMD 760G onboard chip and installed an ATI Radeon HD4350 - but to no avail.
Does anyone know of a workaround? Do you need any further information?
Thanks in advance
OK, I removed the driver from windows update and installed the ATI legacy driver - and now it works.
Seems to be a bug - I created a ticket in mantis now.
