[Qt-interest] Fwd: QT OpenCascade application Problem

[Sujan Dasmahapatra]

Any comment on this srdjan. I am stuck with this ! Back trace is showing
theres some problem with the libTKernel I thinnk so. If this so then is it
an Opencascade bug !. Any suggestion would be highly appreciated.

Thanks
sujan
