[patch, libgfortran] PR31052 Bad IOSTAT values when readings NAMELISTs past EOF
Sat Mar 10 06:30:00 GMT 2007
This problem was not quite what I originally thought. The function test_endfile
was setting the endfile flag to AT_ENDFILE for the test case provided in the PR.
Commenting out test_endfile in st_rewind resolves the test case but regresses
dev_null.f90. All other test cases past. So, it appears that test_endfile is
needed for the special case when rewinding /dev/null. This seems weird to me to
begin with, but how does one determine that a file is /dev/null?
Regardless, the attached patch resolves this issue by adding the additional
condition that the file_length is zero before setting end_file to AT_ENDFILE.
Fully regression tested on x86-64-Gnu/Linux.
On the test case, I will convert the case in the PR to an equivalent testsuite
OK for trunk and then 4.2 after the branch freezes and reopens later?

* io/open.c (test_endfile): Add condition of file_length equal to zero
to prevent incorrect setting of endfile flag to AT_ENDFILE.
(new_unit): Fix typo in comment.
