Teemu,
Having looked at the error report, you may as well increase
your swap space to maybe 3 or 4 GB. Plus when you run the film that
crashes, monitor the process to see if it goes over 2 GB process limit
(if appropriate for AMD64). Did you recompile FSL for 64 bit,
or are you using a downloaded set of executables, and if so which one?
It appears to crash when it is writing out/reading in data for doing the
SUSAN smoothing of the autocorrelation estimates. So worth double checking
any disk space, file i/o issues with your system.
Sorry I can't be anymore specific.
Best regards, Mark.
