[DRE-maint] Bug#1116891: rails: FTBFS with the nocheck build profile

[Santiago Vila]

Package: src:rails
Version: 2:7.2.2.2+dfsg-1
Severity: important
Tags: forky sid ftbfs
User: debian-qa at lists.debian.org
Usertags: ftbfs-nocheck-profile

Dear maintainer:

During a rebuild of all packages in unstable using the nocheck build profile,
your package failed to build.

Below you will find how the build ends (probably the most relevant part,
but not necessarily). If required, the full build log is available here:

https://people.debian.org/~sanvila/build-logs/202509/

A wiki page discussing how to reproduce bugs in this category and
possible solutions is available here:

https://wiki.debian.org/qa.debian.org/FTBFS/Nocheck

(It's a wiki, so you are welcome to contribute)

[ Note: This is RC, but I will wait at least two weeks before raising
the severities, there are a lot of gcc-15 and CMake 4 bugs open now ].

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you could not reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:rails, so that this is still
visible in the BTS web page for this package.

Thanks.
