Bug 2248097

Also just confirmed same segfault happening in Koji s390x rawhide (though of course cabal-install cannot normally be used there due to no network).

Segfault doesn't happen with F37 s390x though.

(Just for completeness: same thing with latest cabal-3.10.2.0 just released:
https://copr.fedorainfracloud.org/coprs/petersen/cabal-install/build/6601582/
)

But I confirmed in Koji that "cabal update" also segfaults

(epel9 also does not segfault of course)

I managed to reproduce in a s390x fedora:39 container:

cabal-install-3.10.1.0-1.fc39.s390x also dumps core inside fedora:39

Reverting F39 to https://kojipkgs.fedoraproject.org//packages/cabal-install/3.6.2.0/3.fc39/s390x/cabal-install-3.6.2.0-3.fc39.s390x.rpm
stops `cabal update` from segfaulting and after that (~/.cabal/packages/ created) current cabal-install-3.8.1.0 no longer segfaults.

Crash is also reproduced with fedora-toolbox:39 toolbox (provided there is no existing ~/.cabal/)

Perhaps more interestingly downgrading from Koji cabal-install-3.8.1.0-1.fc39.s390x
to https://download.copr.fedorainfracloud.org/results/petersen/cabal-install-3.8/fedora-39-s390x/04784966-cabal-install/cabal-install-3.8.1.0-1.fc38.s390x.rpm
also stops the segfault.

Could you also release new packages for F39 including a rebuild of cabal?

Thank you

Seems I didn't push the f39 build into the updates system, ugh

I gave cabal a try and it still fails. Is it possible that cabal-install was still compiled with the broken GHC?

Hm, it was built with ghc-compiler-9.4.5-137.fc39.s390x,
which is supposed to have the fixed...

https://koji.fedoraproject.org/koji/taskinfo?taskID=112716128

Just double-checking: so "/usr/bin/cabal update" segfaults for you, right?
I need to check more carefully then I guess.

Is it because I need to rebuild all the deps too? ;-(
I seem to remember something like that: need to check my notes in gitlab.

Yes, I have tested it in a fresh container, i.e., no old/potentially broken $HOME/.cabal lingering around are whatever.

As I feared: https://gitlab.haskell.org/ghc/ghc/-/merge_requests/11662#note_536725

Sigh

I wonder if the mass-rebuild was even enough to fix this for deps in F40.

Okay I rebuilt cabal-install for Rawhide and next F40, which should fix the problem there.

I can confirm that cabal is working for me on rawhide and next (40).  However, it is still segfaulting on 39 for me.

Okay, thank you.

Yeah, I didn't have time yet sorry - there has been quite a lot of fall out for the F40, and also some pending pandoc CVEs.
So I need more time - but let me know if you consider this is a priority, and I can try to bump it up my to-do list.

Fine for me.  Just wanted to confirm that F40/Rawhide packages are good. Once F39 packages are rebuild I will give them a try, too.

This message is a reminder that Fedora Linux 39 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 39 on 2024-11-26.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '39'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 39 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Sorry, I was not able to find time to fix this for F39.

I was a little surprised to see some segfault happening still in F40, though it could be unrelated perhaps
