Bug ID: 95476
Summary: Reading file of length zero
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: m.diehl at mpie dot de
Target Milestone: ---
There is some ambiguity when reading a file of zero length:
program test
character(len=:), allocatable :: a
a = IO_read('empty.txt')
print*, len(a)
print*, '#'//a//'#'
contains
function IO_read(fileName) result(fileContent)
character(len=*), intent(in) :: fileName
character(len=:), allocatable :: fileContent
integer :: &
fileLength, &
fileUnit, &
myStat
inquire(file = fileName, size=fileLength)
open(newunit=fileUnit, file=fileName, access='stream',&
status='old', position='rewind', action='read',iostat=myStat)
if(myStat /= 0) stop 1
allocate(character(len=fileLength)::fileContent)
read(fileUnit,iostat=myStat) fileContent
print*, mystat
close(fileUnit)
end function IO_read
end program test

According to the comment by S. Lionel, the behavior of gfortran conforms to the
standard
