conver_to_binary_timestamp throws bad_alloc execption

[ingerido]

I encountered the following memory allocation issues when trying to use the tool conver_to_binary_timestamp with the following command:

./convert_to_binary_timestamp < text_graph_file_path > binary_graph_file_path

However, after it runs for a while, it throws an error of

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
Aborted

I'm using the following dataset from SNAP, and I believe the size is not that big with only few megabytes.
