	PR fortran/91926
	* trans-expr.c (gfc_conv_gfc_desc_to_cfi_desc): Correct the
	assignment of the attribute field to account correctly for an
	assumed shape dummy. Assign separately to the gfc and cfi
	descriptors since the atribute can be different. Add btanch to
	correctly handle missing optional dummies.
