[Bug fortran/34594] New: On error, no jump to ERR=<label>

[burnus at gcc dot gnu dot org]

For the following program, the IOSTAT is properly set to /= 0 (namely to -1),
but the ERR= is ignored. If iostat= is not present, a run-time error is shown,
otherwise after the read statement is continued as if nothing had happened.

My test case, based on e73 test case of the Fortran 95 testsuite.

implicit none
integer :: iou, i, ir, TEMP_CHANGES
iou=9
i=44
ir = -42
open(iou,access="direct",recl=1000,status="scratch")
! Variant 1: Gives run-time error instead of jumping to 99
!READ (11, REC = I, ERR = 99) TEMP_CHANGES
! Variant 2: ir is ok, but does not jump to 99
READ (11, REC = I, IOSTAT = IR, ERR = 99) TEMP_CHANGES
print *, 'Should not be reached; ir = ', ir
stop
99 continue
if(ir == 0) then
  print *,'ERROR: ir should not be 0'
  stop
end if
print *, 'OK'
end
