It's a bug in that version of gcc.  The solution is a more recent version.

Hi Dan

The latest version was 5.6 I tried with that.

As per the INSTALL file I also tried the specific version 4.88

Both failed to compile

I suspect you are not really using the g++ version that you think you are using.

Hopefully within a couple of days, though, we'll add a patch so that it even works with the "bad" versions of gcc.  I'm not sure exactly which version are affected.

[Daniel Povey]

quick fix is to change 'auto' on that line to 'typename Arc::StateId'.
