[Insight-users] Problems reading 2D analyze files

[Richard Beare]

Hi,
I haven't tracked down the source of the problem yet, but thought I'd
send a quick summary in case anyone recognises it.

Using new versions of ITK I'm having trouble reading 2D analyze files.
In ImageViewer (or any python scripts) I get a segmentation fault on
reading. gdb reports the following:

Program received signal SIGSEGV, Segmentation fault.

I am able to load the same image successfully using a much older
version of itk and ImageViewer compiled from cvs back at the end of
September.

The current version seems to read 3D images without any problems.

Any ideas?
