[Insight-users] [ITK Community] Crashing in debug mode

[Luis Ibanez]

Kent,

Thanks adding the two output images.

One of the main differences between Debug and Release builds,
is that in Debug mode, the compiler tends to initialize variables.

It may be the case here, that the code has an uninitialized variable,
and the compiler is setting it to zero in Debug mode, while leaving
it uninitialized in Release mode.


Just an idea....
