From reading just this source file I'm not sure emacs supports long paths.
How long is your path? Maybe you can show what it looks like?

There might be a buffer overflow happening in get_volume_info(), this
line looks suspicious to me:
3488      strncpy (temp, name, root_len);

If it turns out the problem is not in get_volume_info(), you might have
to step further back with 'reverse-next' to see where it was called from.
