At the tail of function 're_search_2' in src/regex.c (GNU
Emacs 18.55), I found the following strange code:

      if (0 <= val)
	{
	  if (val == -2)
	    return -2;   <---
	  return startpos;
	}

The line indicated by an arrow is never executed.  It should
be:

      if (0 <= val) return startpos;
      else if (val == -2) return -2;
