Hi Mark,
We ran into the FLIRT 5.0 segmentation violation issue on RedHat 9. The
images that cause the problems are located at:
http://www.nbresearch.com/data/FlirtSegViolationImages.zip
This file contains two sets of images: T1 (high resolution) and ref-T1 (low
resolution)
The command that we used which triggers the segmentation error is:
flirt -in T1 -ref ref-T1 -out foo
The interesting thing is that the problem doesn't occur for every T1 image
we have and it only occurs when trying to register the higher resolution T1
image to the lower resolution reference image.
In any case, running with verbose set at a high level shows that the
problem always occurs just after:
>> copy U UE
>> if MAXDOF > 9
>> clear U
>> if MAXDOF > 9
>> optimise 12 UE:1 0.0 0.0 0.0 0.0 0.0 0.0 0.0 rel 2
Coarse rotation samplings are:
-1.570796 -0.523599 0.523599 1.570796
-1.570796 -0.523599 0.523599 1.570796
-1.570796 -0.523599 0.523599 1.570796 ...
If any further information to debug the problem is needed, then please let
me know.
