[vtkusers] vtkStringArray problem

[Cory Quammen]

Rich,

Hmm, I don't see anything obviously wrong with your code. I have
attached a sample program that creates a vtkStringArray like you are
doing and it runs fine.

Could you try running your code through a memory checker such as
valgrind to see if there might be memory errors elsewhere that
manifest in this section of the code?

Thanks,
Cory
