[ITK-users] Floating point exception (core dumped) ConnectedComponentFilter

[Bradly Lowekamp]

Hello,

Certainly more information about the nature of the exception would be good.

If this is indeed an C++  exception either std::exception of itk::ExceptionObject based, the try catch block will work. 

However floating point exceptions are usually a difference beast from C++ exception objects. Floating point exception occur during floating point computation in the FPU [1]. Generally the FPU can be configure to silently assign a predefined floating point value such as “nan”, or a signal can be generating terminating the program like in your case. The option can usually be configured with compilation flags, the run-time environment or the program itself.

HTH,
Brad
