[vtkusers] Fwd: Re: Heap corruption | vtkLookupTable?

Wed Jan 27 16:15:58 EST 2016

Hi Cory,

Sorry that I did not respond earlier. Overlooked your e-mail. Thank you
for your reply

Now using

OS: Windows 10 x64 IDE: MS VS 2015 VTK: 7.0.0.rc2 x64 build

Still receiving the same error message at the same place:

HEAP CORRUPTION DETECTED: after Normal block (#218683) at
0x00000286C6D22350. CRT detected that the application wrote to memory
after end of heap buffer.

No idea how to create a CMakeLists.txt file. Please advise.

Regards,

Audrius
