Core dumped at testing part of news dataset example about starspace HOT 6 CLOSED

Looks like I was hit by bug in libstdc++ - model generated with starSpace built with 4.8, runs perfectly on another machine where starSpace is built with GCC6

from starspace.

@alexott does switching to 4.8 solve your problem? Can I close the issue now? Thanks.

@alexott Thanks. You can also try the .tsv format model in testing (instead of passing --model='model', try --model='model.tsv', in ./starspace test). Closing the issue for now but feel free to re-open if you find out more about the root cause.

@ledw I found the root cause - the problem is that ntokens_ in dict.h is declared as int32_t, but it's written (dict.cpp:98) & read (dict.cpp:114) as int64_t, overwriting the next fields in memory...

@alexott Thanks a lot! Fixed in cce4d07
