SEGV with boost-libs-1.79.0

[yurivict]

After upgrading boost-libs from 1.72.0 to 1.79.0 qbittorrent now crashes:

Downstream bug report.

Version: 2.0.8
FreeBSD 13.3

The latest 2.x code revision doesn't crash when built with -std=c++17.

[yurivict]

Maybe you should just add -std=c++17 and make a new release?

[userdocs]

The releases are just the source code so no need to make a new release. It would just be docs about building

I think there have already been examples of problems with cxx14 and newer version of boost and libtorrent v2 that using cxx17 has resolved. So maybes it's just better to advise using cxx 17 where possible.

[arvidn]

it smells like an ABI issue, which could be caused by a number of build flags differing between libtorrent, boost and qbittorrent.

I don't have any issues on Ubuntu. After updating boost, did you also rebuild libtorrent and qbittorrent?

[userdocs]

I think most of the examples were on non debian based systems, like the gentoo, alpine and there was one or two others I think, openbsd maybe.

#6567

#6468 (comment)

Maybe a non gcc issue or something where the standard used is part of the reason why the segfault happens.

This is what I was referencing.
