[Insight-users] itkImageMaskSpatialObject segmentation fault

[Bradley Lowekamp]

Hello,

I don't see anything obviously wrong with your code, but I haven't recently used that class myself.

Do you know how to run the program in  gdb to determine where the segfault is happening? A stack trace is quite useful for tracking down this type of error.
