If the following program is compiled with -gnatVa and an empty file inputfile.dat, then it should terminate with an End_Error exception: raised ADA.IO_EXCEPTIONS.END_ERROR : s-stratt.adb:250 But before this patch, it gets a validity check, since there is a junk validity check on the OUT parameter for the Read attribute. pragma Initialize_Scalars; with Ada.Streams.Stream_IO; use Ada.Streams.Stream_IO; procedure Tic_Read is Test_File : File_Type; Test_Stream : Stream_Access; Float_Value : Long_Float; begin Open (Test_File, In_File, "inputfile.dat"); Test_Stream := Stream (Test_File); Long_Float'Read (Test_Stream, Float_Value); Close (Test_File); end Tic_Read; Tested on i686-pc-linux-gnu, committed on trunk 2008-08-22 Robert Dewar <dewar@adacore.com> * exp_attr.adb: (Expand_N_Attribute_Reference): No validity checking on OUT parameter of Read or Input attribute.
