Segmentation fault with binutils 2.28.1

Segmentation fault with binutils 2.28.1

[Steven Penny]

Reposting because it is a new month. Here is a demonstration of the problem:

    $ cat z.cpp
    #include <iostream>
    main() {
     std::cout << "cout test\n";
    }

    $ x86_64-w64-mingw32-g++ -static -o z z.cpp

    $ ./z
    Segmentation fault

Who is in charge of maintaining this package? Can we just upgrade to
latest binutils?

no top posting on this list. Please.


the list of maintainers is at
https://cygwin.com/cygwin-pkg-maint


Are you sure that an upgrade solve the problem ?
I am sure Jon will appreciate any constructive help.

I assume it is one of the reason why the compiler and binutils
you are using are still in test and not current

@ mingw64-x86_64-binutils
version: 2.25.0.1.23f238d-1
[test]
version: 2.28.1.12c1f20d-1

@ mingw64-x86_64-gcc-g++
version: 5.4.0-3
[test]
version: 6.3.0-1

As you shifted the target from g++ to binutils,
do you have evidence that 2.29 will solve the issue ?

Jon always appreciates constructive help.

Marco

Notice carefully that I did not saying anything about GCC 6.3.0 in this thread.
Also notice that you are incorrectly assuming that I am using GCC 6.3.0. The
binutils in question does not work with either 5.4.0 nor 6.3.0.

> As you shifted the target from g++ to binutils

I did this because binutils is the problem, not GCC:

- http://github.com/Martchus/tageditor/issues/23

> do you have evidence that 2.29 will solve the issue ?

It seems that both 2.28 and 2.29 both work, so instead of trying to
troubleshoot we should probably just build a newer version and release that as
test:

Steven,
you wrote nothing at all.
So it is difficult to understand what is your exact issue as in
the past you blamed the compiler.
Error report should be clear and complete;
only links to other place are not enough.

I saw the comment from Martchus
"Note that when I had been using mingw-w64-binutils 2.28 (before recent 
update to 2.29) I didn't encounter this issue. I never tried 2.28.1."

So it does not seem an issue specif of 2.28

Have you built it ? Or are you only asking Jon to dedicate his time ?

Last time I had issue with cygwin binutils 2.25, I built the 2.28.90
and I verified that was solving the issue I saw.
I was not just expecting Jon to debug it alone.

I wrote it 4 times:

Here though, let me write it 5 now:

    $ cat z.cpp
    #include <iostream>
    main() {
      std::cout << "cout test\n";
    }

    $ x86_64-w64-mingw32-g++ -static -o z z.cpp

    $ ./z
    Segmentation fault

Yes, I discovered new information, so I modified the email subject to reflect
that. Would you rather me continue to blame the complier, or try to help
diagnose the problem?

See above - also notice carefully that example was included in my previous post
as well

No one but you has said that 2.28 has a problem. What Martchus actually said
was:

- 2.28   working
- 2.28.1 never tried
- 2.29   working

> Have you built it ?

No

> Or are you only asking Jon to dedicate his time ?

Hm. Last I checked I have already made at least 10 posts on this issue:

Maybe your sense of time is distorted.

Good for you, but I dont have to build anything to verify the issue - I narrowed
the problem to a single package, and tested with "Test" and "Current" versions.
"Current" works - "Test" fails.

So we could patch "Test", but since a newer version is already available (2.29),
the sane thing to do would be to just upload a newer test version and probably
bypass the problem altogether. If you want to waste your time making a build in
this case that is your business, but dont put that bad advice off on me when I
have already diagnosed the problem.

Guys,

If someone could show me some instructions on how to build and release
binutils for CYGWIN, I'm happy to do it this week.

Cheers.

Hi 叶雨飞,
only the maintainer can release it.

However to see how to build and test it, the easy way
is to download the cygwin source package
    mingw64-x86_64-binutils-2.28.1.12c1f20d-1-src.tar.xz
using setup or directly from a mirror.

The file contains the upstream source used for the build,
a patch and the cygport file.

$ tar -tf mingw64-x86_64-binutils-2.28.1.12c1f20d-1-src.tar.xz
mingw64-x86_64-binutils-2.28.1.12c1f20d-1.src/
mingw64-x86_64-binutils-2.28.1.12c1f20d-1.src/binutils-gdb-2.28.1.12c1f20d.tar.bz2
mingw64-x86_64-binutils-2.28.1.12c1f20d-1.src/config-rpath.patch
mingw64-x86_64-binutils-2.28.1.12c1f20d-1.src/mingw64-x86_64-binutils.cygport


cygport is the standard method for building and maintaining packages for
the Cygwin distribution.
https://sourceware.org/ml/cygwin-announce/2017-05/msg00042.html

Attached for your convenience the same patch and the modified
mingw64-x86_64-binutils.cygport for 2.19.1.

Assuming you have cygport and all the needed tools and libraries,
these commands will download the upstream source file and
build the full cygwin package

$ cygport mingw64-x86_64-binutils.cygport download
$ cygport mingw64-x86_64-binutils.cygport almostall

The build took ~ 1 hour on my PC.
I have not yet tested it.

Regards
Marco

That is the problem.
It costed me one hour of my time, you could have done by yourself.


Jon,
let me know if you need help on updating binutils.

So short term use binutils 2.25 with test gcc-6.3
