[Insight-users] itkGradientMagnitudeRecursiveGaussianImageFilter with no input segfaults ITK

[Gaetan Lehmann]

Charl,

Many classes are currently susceptible to produce segfault in ITK. All classes 
and method names you may found in 
http://voxel/darcsweb/darcsweb.cgi?r=WrapITK;a=headblob;f=/Python/Tests/returnedTypeCoverage.py 
cause segfault in some conditions.
I hope fixing all those problem is the next challenge for ITK, after the 
concept check revolution.

Gaetan
