I see a very similar problem with a slightly modified piece of testcode on
version 4.7.2. Not sure if it is exactly the same, but probably related to the
already patched issue. My testcode:
program testtransfer
integer, parameter :: r8_ = Selected_Real_Kind(15,307) ! = real*8
integer, parameter :: nbytes_r8_ = 8
real(r8_) :: val
character(len=1), dimension(16) :: byte_array
byte_array(:) = ' '
call mytest(byte_array,val)
print *,"val: ",val
contains
subroutine mytest(byte_array,val)
character(len=1), dimension(16), intent(in) :: byte_array
real(r8_),intent(out) :: val
val = transfer(byte_array(1:nbytes_r8_),val)
end subroutine mytest
end program testtransfer
Results:
>gfortran -Wall -o transfer_problem transfer_problem.F90
transfer_problem.F90:15.19:
val = transfer(byte_array(1:nbytes_r8_),val)
1
Warning: Intrinsic TRANSFER at (1) has partly undefined result: source size 1 <
result size 8
>
This occurs for this version:
>gfortran --version | head -1
GNU Fortran (GCC) 4.7.2 20120921 (Red Hat 4.7.2-2)
on my Fedora17 system. (package gcc-gfortran-4.7.2-2.fc17.x86_64)
The problem is not present in:
>gfortran --version | head -1
GNU Fortran (GCC) 4.6.3 20120306 (Red Hat 4.6.3-2)
on a Fedora16 system. (package gcc-gfortran-4.6.3-2.fc16.x86_64)
