Multiple characters in a label cause a segfault

[lorenlugosch]

When I try to use a multiple-character string as a label, I get a segfault.
For example:

import torch
import ctcdecode
labels = ["_", "SIL", "A"]
decoder = ctcdecode.CTCBeamDecoder(labels, blank_id=0)
decoder.decode(torch.randn(3,3,3))

triggers a segfault, whereas

import torch
import ctcdecode
labels = ["_", "A", "B"]
decoder = ctcdecode.CTCBeamDecoder(labels, blank_id=0)
decoder.decode(torch.randn(3,3,3))

does not. Is it possible to do this somehow?
