Package: gfortran-4.6
Version: 4.6.2-12
Severity: normal

Dear Maintainer,

Formatted read statement cannot parse the minimum integer by a program
compiled by gfortran-4.6.

I compiled the following test program with no options,
----------------------------------------
  program test_int_min
    implicit none
    integer :: i
    integer :: ios
    read (*, *, IOSTAT=ios) i
    if (ios.ne.0) then
       write (*, *) 'ERROR', ios
    endif
    write (*, *) i, -i, -i-1, -i-2
    stop
  end program test_int_min
----------------------------------------

and executes as follows.

----------------------------------------
% gfortran test_int_min.f
% echo 2147483647  | ./a.out
  2147483647 -2147483647 -2147483648  2147483647
% echo -2147483647 | ./a.out
 -2147483647  2147483647  2147483646  2147483645
% echo -2147483648 | ./a.out
 ERROR        5010
           0           0          -1          -2
----------------------------------------

You see we can compute, store, write the actual minimum integer
-2147483648 in the program, but fail to read it.
Similar error occurs also when using a namelist.

I suspect that gfortran converts a string of a number to the absolute
value before sign treatment, which causes overflow of integer.

Best regards,
