[Gate-users] segfault ITK multithreader

[Simon Rit]

Hi,
I'm not sure but I had similar issues at some point. I first fixed
something in ITK:
http://review.source.kitware.com/#/c/21937
Then the problem was a bit more explicit, it could not create enough
threads. I never explained it in my case (see:
https://public.kitware.com/pipermail/insight-users/2017-January/054167.html)
but turning on ITK_USE_THREADPOOL at compilation of ITK fixed the problem.
Can you turn on ITK_USE_THREADOOL with the latest ITK to see if that solves
your issue?
Note that you can always turn off multithreading using the env variable:
export ITK_GLOBAL_DEFAULT_NUMBER_OF_THREADS=1
Hope this helps,
Simon
