WebMay 2, 2014 · Viewed 1k times. 0. I am using two Boost threads, each of which uses different FFTW plan (example: thread 1 uses 'plan_fft' and thread 2 uses 'plan_ifft'). When I run only one thread (thread 2), it works perfectly, but when I run both threads, then I am getting a segmentation fault. I think it may be because of creation plan is not thread safe.
