           Summary: Wrong repeat count in error message for REPEAT
                    intrinsic
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: thenlich@users.sourceforge.net


If the REPEAT intrinsic is given a negative NCOPIES argument at runtime, in the
resulting error message an erraneous value is printed.

Example:
program test_repeat
    integer :: i = -1
    print *, repeat("x", i)
end program test_repeat

$ ./a.out
At line 3 of file test_repeat.f90
Fortran runtime error: Argument NCOPIES of REPEAT intrinsic is negative (its
value is 4294967295)

Expected result:
At line 3 of file test_repeat.f90
Fortran runtime error: Argument NCOPIES of REPEAT intrinsic is negative (its
value is -1)

On x86_64-apple-darwin10, the test returns

Fortran runtime error: Argument NCOPIES of REPEAT intrinsic is negative (its
value is -1)

with -m64 (default). The value returned with -m32 depends on the version:
72057598332895231 for 4.4.4 and 4.5.2, 118064355999743 for 4.6.0 (r169227), and
4294967295 for trunk (r173786).

With -m64:

_gfortran_runtime_error_at (&"At line 3 of file foo.f90"[1]{lb: 1 sz: 1},
&"Argument NCOPIES of REPEAT intrinsic is negative (its value is %lld)"[1]{lb:
1 sz: 1}, (integer(kind=8)) D.1547);

With -m32:

_gfortran_runtime_error_at (&"At line 3 of file foo.f90"[1]{lb: 1 sz: 1},
&"Argument NCOPIES of REPEAT intrinsic is negative (its value is %lld)"[1]{lb:
1 sz: 1}, (<unnamed-signed:32>) D.1501);


Thus, in both cases the argument value is wrongly cast; cf. POSIX's printf(3):

       ll (ell-ell)
              Specifies  that  a  following d , i , o , u , x , or X
              conversion  specifier  applies  to  a  long  long   or
              unsigned  long  long  argument;  or that a following n
              conversion specifier applies to a pointer  to  a  long
              long argument.

32 bit, 2.6 kernel,  revision 183881, message is correct.
Should this be closed or is it an X86-64 thing ?
