Bug ID: 102699
Summary: Stream access input/output
Product: gcc
Version: 10.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: [email protected]
Target Milestone: ---
Consider the following Fortran program:
!------------------------
program streamio
implicit none
integer :: k(5) = [5_4, 4_4, 3_4, 2_4, 1_4]
open(10, file="123.txt", form="formatted", access="stream")
! open(10, file="123.txt", form="formatted")
write(10, "(A6)") '098765'
write(10, "(A6)") '239345'
write(10, "(A6)") '123789'
write(10, "(A6)") '789509'
write(10, "(A6)") '543210'
rewind(10)
read(10, "(I2)") k(1)
read(10, "(I3)") k(2)
read(10, "(I2)") k(3)
read(10, "(I3)") k(4)
read(10, "(I1)") k(5)
print *,k
end program
!------------------------
Compiled with gfortran 10.1.0.
Regardless of whether the access uses "stream",the result is the same.
the result:
9 239 12 789 5
the file:
098765
239345
123789
789509
543210
IMHO, when using access="stream", the result should be
9 876 52 393 4
and the file shoule be
098765239345123789789509543210
is it a bug or is there something wrong with my understanding?
