Hi Iain,

Is there any chance you are simply running out of
RAM? The program is allocating 3.3 GB of RAM, or
more, at the time of the crash. Also, it is using
memory mapping.

That it does not crash without _IM is not a big
surprise, as there does not seem to be so much
data, just a huge model.

So how much RAM does the system have, and what
OS and version are you using?

Also, consider setting AFNI_NOMMAP to YES, and
see how that goes.
