re PR fortran/28129 (gfortran -fbounds-check: Shows invalid array out of bounds error)

Browse Source 
PR fortran/28129

	* trans-array.c (gfc_trans_array_bound_check): Add a locus
	argument, and use it in the error messages.
	(gfc_conv_array_index_offset): Donc perform bounds checking on
	the last dimension of assumed-size arrays.

	* gfortran.dg/bounds_check_4.f90: New test.
