Discussion:
Describe the bug I'm trying to use latest unstable branch in a flake that contains ROOT 6.22.08. The package contains a program . When I try to launch that, I got the following segmentation fault, hinting on build time and runtime conflict for : To Reproduce Steps to reproduce the behavior: from Expected behavior The program should run w/o problem Additional context The command line runs OK, provided that no graphical interface is invoked. Same segmentation fault would occur if in a shell, I do the following: Notify maintainers <!-- Please @ people who are in the list of the offending package or module. If in doubt, check for whoever last touched something. -- Metadata Please run and paste the result. Not sure if this is useful, as I tried to install as part of my flake yet I still get this: system: host os: multi-user?: sandbox: version: channels(root): nixpkgs: Maintainer information:
Can you reproduce the crash with ?
Yes:
I don't have an access to NixOS at the moment to reproduce. Do you think you could git-bisect this?
Yes. I'll try to do this sometime this week, if I have time. Just to be sure, everything is OK on macOS?
Yes, it works great:
I did a poorman's bisect with : I think the commit that breaks ROOT is . The commit immediately before that still has a working ROOT (6.18).
On a side, I first tried with the following: But complains: Do you have any suggestion to make this automated bisect work?
git-bisect expects certain return codes to be returned. Perhaps you could try wrapping it in
That is helpful. Google says this is an old problem [1], so it has probably to do with incomplete afterimage unvendoring. [1] https://root-
In the end, the problem was this one: https://root-
Wow, this is a very old "problem" then. I guess previously was not used as a build input so that we never noticed this.
