[vtk-developers] Long standing freak VTK tear down crash

[Sean McBride]

Hi all,

For literally years, we have received rare, intermittent, and non-reproducible crash reports from our customers involving VTK tear down.  The backtrace is always something like:

Application Specific Information:
*** error for object 0x111b15930: double free

Thread 0 Crashed:: Dispatch queue: com.apple.main-thread

6   com.rogue-research.brainsight2	0x00000001009bfae1 vtkCocoaRenderWindow::~vtkCocoaRenderWindow() + 273
.... etc.

I know there's next to nothing to go on here :(, but anyone else ever see this?  Or have any ideas?  We've seen it in-house a couple of times, but have never caught it with valgrind or similar memory debugging tools. :(

Thanks,
