re PR fortran/35864 (Revision 133965 broke gfortran.dg/initialization_1.f90)

2008-04-15  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/35864
	* expr.c (scalarize_intrinsic_call): Reorder identification of
	array argument so that if one is not found a segfault does not
	occur.  Return FAILURE if all scalar arguments.
