[MINC-development] minctracc and large(ish) input files

[Andrew Janke]

Hi all,

Has anyone else had minctracc fail (segfault) on sizeable but not
massive input files?

In my case the input file is big but not ginormous:

file: b.mnc
image: unsigned byte 0 to 255
image dimensions: zspace yspace xspace
    dimension name         length         step        start     dircos
    --------------         ------         ----        -----     ------
    zspace                    150          0.5       -124.2     0 0 1
    yspace                   1311          0.5      -327.15     0 1 0
    xspace                    679          0.5       -169.2     1 0 0

And this will segfault it:

   ~/cvs/registration/mni_autoreg/minctracc/Main/minctracc -no_super
-transformation ident.xfm -clobber -nonlinear -iterations 1 -step 32
32 32 -debug b.mnc b.mnc /tmp/out.xfm

It seems to die while doing the amoeba setup step but this is likely
just memory being overstepped from somewhere else.

Anyone (Claude and his big brain!) have any insights as to which
particular rabbit hole I should go looking down first?
