[Bug fortran/41168] incorrect processing of formatted records in mingw port
--- Comment #11 from jvdelisle at gcc dot gnu dot org 2009-09-11 05:38 --- PR41328 was submitted which has a little bit easier test case to use while not requiring mingw environment. So, I am closing this bug as the duplicate even though it was reported here first. A patch has been submitted for approval. See: http://gcc.gnu.org/ml/fortran/2009-09/msg00062.html Thanks much for this bug report. The test case was very useful. In fact, I was onto the problem before the other PR was reported. *** This bug has been marked as a duplicate of 41328 *** -- jvdelisle at gcc dot gnu dot org changed: What|Removed |Added Status|ASSIGNED|RESOLVED Resolution||DUPLICATE http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41168

--- Comment #8 from michael dot a dot richmond at nasa dot gov 2009-09-08 15:21 --- (In reply to comment #7) Is the problem described at http://gcc.gnu.org/ml/fortran/2009-09/msg00046.html the same or a different one? There, it is claimed to be a 4.5 regression. I verified the problem described in http://gcc.gnu.org/ml/fortran/2009-09/msg00046.html. I found that my bug does not occur under gfortran 4.4. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41168

--- Comment #9 from jvdelisle at gcc dot gnu dot org 2009-09-09 00:58 --- It is not clear whether we have two bugs or one here yet. I am investigating. One way to possibly reproduce this on linux machines is to define HAVE_CRLF in libgfortran/io/io.h. This way, all files affected by that define will be re-compiled. I am trying this and will report back if i can reproduce the problem. (I too have still been unable to build a mingw compiler. I tried an automatic script pointed out by Kai and Nightstrike and it failed. I never give up.) :) yet -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41168

--- Comment #4 from fxcoudert at gcc dot gnu dot org 2009-09-03 14:19 --- I can confirm I can reproduce this bug with an darwin-to-mingw cross-compiler, and running the executable under wine. I can also confirm that it's about the REWIND statement: if you have already run the test program once, you can recompile it without the WRITE and the REWIND, using the already existing testcase. Then, it passes OK. It's probably some bad counting of position on platforms with HAVE_CRLF. To investigate, it should be possible to build such a faulty linux compiler by forcing HAVE_CRLF to be true. -- fxcoudert at gcc dot gnu dot org changed: What|Removed |Added CC||fxcoudert at gcc dot gnu dot ||org Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|-00-00 00:00:00 |2009-09-03 14:19:20 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41168

--- Comment #5 from michael dot a dot richmond at nasa dot gov 2009-09-03 18:12 --- (In reply to comment #4) It's probably some bad counting of position on platforms with HAVE_CRLF. To investigate, it should be possible to build such a faulty linux compiler by forcing HAVE_CRLF to be true. I tried to do this in the i686-pc-linux-gnu port of gfortran. In the file libgfortran/config.h.in I changed #undef HAVE_CRLF to #define HAVE_CRLF. When I built gfortran, the change was propagated to libgfortran/config.h. But when I ran the test case it created a file with standard Linux carriage control. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41168
