[Neurodebian-users] fslview segmentation fault

[Yaroslav Halchenko]

fslview has quite a bit of not fixed quirks (e.g. inability to deal with
int8 dtype niftis etc).  Since there is no proper bugtracking (besides
Debian's [1]) for it AFAIK -- we have no formal record of all of them.

you might get a better idea if you run it via gdb and checkout the crash
stack:

gdb fslview
type r<enter>

and when crashes, it no trackback, type 'bt', and share

alternative to hint the problem might be to run via valgrind,

sudo apt-get install valgrind
valgrind fslview

it will be slow but can pin point to specific problems with memory
access etc
