[IGSTK-Developers] Sandbox dynamic memory errors

[David Gobbi]

Hi All,

The dynamic analysis dashboard checks for the sandbox have been showing 
errors for the last week or so.
The culprits seem to be the DICOMImageReader, the recent TimeStamp 
changes, and the View2D.
Here is a summary:

DICOMImageReader in igstkAnnotation2DTest, maybe the string isn't 
initialized:

UMC ==4273== Conditional jump or move depends on uninitialised value(s)

==4273== 

The igstkCTImageSpatialObjectReadingAndRepresentationTest and igstkObliqueImageSpatialObjectRepresentationTest
show nearly identical errors to the above.

TimeStamp or Transform or Tracker in igstkSpatialObjectTest.  The timestamp is being set using an uninitialized variable.

View2D::PrintSelf seems to be printing an uninitialized value in igstkViewTest:
