[vtkusers] QVTKWidget , Application crashes on MS Compiler 64Bit Release ?

[Ashika Umanga Umagiliya]

Hi John,

Thanks for the tip.
I have both Debug and Release builds of VTK.I link relevant libraries depend
on the build.
I don't use VS for my development.I use Eclipse CDT / CMake /NMAKE on
Windows .
I  am wondering whether this is a compiler related issue , because Release
build using MINGW works fine.

thanks
umanga
