re PR libfortran/27524 (-fbounds-check interacts with array function)

Browse source 
PR fortran/27524

	* trans-array.c (gfc_trans_dummy_array_bias): Don't use stride as
	a temporary variable when -fbounds-check is enabled, since its
	value will be needed later.

	* gfortran.dg/bounds_check_1.f90: New test.
