resolve_ref() calls resolve_substring() but failed to check
its return value.  This patch does the check.

2011-10-15  Steven G. Kargl  <kargl@gcc.gcu.org>

	* resolve.c (resolve_ref): Check return value of resolve_substring().

 
2011-10-15  Steven G. Kargl  <kargl@gcc.gcu.org>

	* gfortran.dg/substring_integer_index.f90: New test.
