Segmentation fault in tblis_tensor_mult

[spneville]

I am encountering segfaults when calling tblis_tensor_mult.

Here is a simple example:

`using TBLIS

n = 2

A = Array{Float64}(undef, n, n, n)
B = Array{Float64}(undef, n, n, n)
C = Array{Float64}(undef, n, n, n, n)

Atblis = tblis_tensor(A, 1.0)
Btblis = tblis_tensor(B, 1.0)
Ctblis = tblis_tensor(C, 1.0)

tblis_tensor_mult(Atblis, "abc", Btblis, "cde", Ctblis, "abde")`

which produces the following error:

`nt: 12

[9585] signal 11 (128): Segmentation fault
in expression starting at /home/simon/calculations/TBLIS_testing/test.jl:13
Allocations: 1 (Pool: 1; Big: 0); GC: 0
Segmentation fault (core dumped)`

In case it helps, here is my Julia environment:

Thanks for any help.

Hi spneville,

The segmentation fault issue should be fixed by this PR #20

Best,
