<div><font><font face="verdana,sans-serif">I am trying to migrate to latest VTK, but my project crashes when using git version of VTK (also v5.8). Currently I am using v5.6.1. Win7 x64, ITK4 (but I think the same was happening with 3.20 last year), VS2010, QT 4.8 (similarly with 4.7).</font></font></div>

I tested this at home, which is a pretty clean system (only one version each of dev libs and tools, not 3-5 versions each like at university).</span></div>
<div><span style="font-family:verdana,sans-serif"><br></span></div><div><span style="font-family:verdana,sans-serif">Can someone verify this? If it is not a bug in VTK or itkVTKglue, what am I doing wrong?</span></div><div>
