This is to re-open bug no. 19064. I apologize for doing it in this fashion, but
I do not have access to my old account from which I opened 19064 in 2004.
I have not been using gfortran for a few years, and it seems that in my absense
the bug has crept back in. Version 4.4.3 of gfortran appears to be broken
again, as indicated in the original report. [The bug can be circumvented by
inserting a newline at the end of the data file, which might be a hint as to
how it could be fixed.]

> This is to re-open bug 19064.
> Version 4.4.3 of gfortran appears to be broken again
Seems to work here. At least on my x86_64-unknown-linux-gnu the test case of PR
19064 comment 0 seems to work with GCC
- 4.6.0 20100716 (experimental) [trunk revision 162255]
- 4.5.1 20100519 (prerelease) [gcc-4_5-branch revision 159556]
- 4.4.5 20100513 (prerelease) [gcc-4_4-branch revision 159367]
- 4.2.1
- 4.1.2 20070115
Therefore,
(a) Can you try with a newer version of gfortran,
cf. http://gcc.gnu.org/wiki/GFortranBinaries
(b) For the test file in PR 19064: Are there special line breaks (carriage
return vs. new line) or is there no tailing new line character? Or are there
tabs? Is the architecture still i686-pc-linux-gnu?
Regarding (a): One possibility could be that is was broken only for a short
time - though somehow I find this less likely for a release branch (like your
4.4.3) than for the trunk, but it is possible and does happen.
...
(b) is partially superseded by your attachments. Though, I still cannot
reproduce it.

Works for me on powerpc-apple-darwin9 (4.2.4, 4.3.4, 4.4.2, 4.5.0, and trunk)
and x86_64-apple-darwin10.4 (4.4.4, 4.5.0, and trunk).

Thanks for the quick response. Let me clarify: The data file contains no
trailing newline or carriage return - if a newline is appended the problem
disappears.
My setup is (default Ubuntu 10.0.4 install):
Target: i486-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Ubuntu 4.4.3-4ubuntu5'
--with-bugurl=file:///usr/share/doc/gcc-4.4/README.Bugs
--enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --enable-shared
--enable-multiarch --enable-linker-build-id --with-system-zlib
--libexecdir=/usr/lib --without-included-gettext --enable-threads=posix
--with-gxx-include-dir=/usr/include/c++/4.4 --program-suffix=-4.4 --enable-nls

--enable-checking=release --build=i486-linux-gnu --host=i486-linux-gnu
--target=i486-linux-gnu
Thread model: posix
gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5)
I will try other versions of gfortran when I get a chance.

BTW: One obvious difference is that my system is 32 bit (x86 vs. x86_64). I
don't have a x86_64 system handy today to test that hypothesis.

(In reply to comment #5)
> gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5)
I think the problem was only present between the 4.4.2 release (2009-10-15) and
4.4.4 (2010-04-29).
Most likely it was caused by the commit for PR 43265 (2010-03-17, in 4.4.4 (!)
not in 4.4.3 - ?!?) and fixed as PR 43517 (2010-03-25). The 4.5 trunk was
affected from 2010-03-09 to 2010-03-25). But there were also a couple of other
commits.

Unlikely. Additionally, with "gfortran -m32" (which uses the x86 library) it
also works for me.

My ppc build is 32 bit by default and I have checked that I don't have trailing
end of line.

burnus,
Thanks for investigating. I have verified that the bug is indeed fixed in
4.6.0:
gcc version 4.6.0 20100407 (experimental) [trunk revision 158083] (GCC)
Hope the fixed version makes it into Ubuntu soon... Any idea who to lean on to
encourage that?
I changed the status to FIXED. Is that the correct status to use for this
situation?
Rasmus
