together wih a discussion of the problem, is OK'd for trunk and, in a

Thanks to both of you.

	PR fortran/30003
	* gfortran.dg/allocatable_function_1.f90: Increase the number
	of expected calls of free to 10; the lhs section reference is
	now evaluated so there is another call to bar.  Change the
	comment appropriately.
