[Nix-dev] Packaging Torch

[Sergey Mironov]

Unfortunately, the Torch build from
https://github.com/grwlf/torch-distro has a Segfault problem.

$ th
th> N = 5
                                                                      [0.0000s]
th> A = torch.rand(N, N)
                                                                      [0.0002s]
th> A = A*A:t()
Segmentation fault (core dumped)

Core dump shows that it is the luajit who cause the fault. The source
of a problem is still a mystery.
