After building 24.3 rather than relying on the binary provided by my 
distro I now see the issue in both versions, so I think you are right to 
say the problem is with one of the dependencies, rather than with Emacs.

Perhaps I can find a way to reproduce an issue on libotf / m17n-flt 
separately and raise it in the appropriate place.

Thanks,
Matt
