On segmentation faults happening in the line.cpp Update method

[benelot]

With one of my network graphs, I had several segmentation faults occurring, which I could locate within the update method of LINE. The problem is that if the embeddings get very large in magnitude within some of the dimensions, the variables start to overflow and then the sigmoid method segfaults. I could mitigate the problem by setting "typedef double real;" instead of "typedef float real;" to use double precision instead of single precision. This resolved the segmentation faults, at least within my networks because of the enlarged variable space, however, when the embeddings are concatenated in the end, it again results in overflown embeddings. To solve the problem completely, it was necessary to write my own concatenate method. Just in case somebody runs into the same problems.
