[DRE-maint] Bug#996227: ruby-ferret: FTBFS with ruby3.0: index.h:595:25: error: width of ‘is_compressed’ exceeds its type

[Antonio Terceiro]

Source: ruby-ferret
Version: 0.11.8.7-2
Severity: serious
Justification: FTBFS
Tags: bookworm sid ftbfs

Usertags: ruby3.0

Hi,

We are about to enable building against ruby3.0 on unstable. During a test
rebuild, ruby-ferret was found to fail to build in that situation.

To reproduce this locally, you need to install ruby-all-dev from experimental
on an unstable system or build chroot.

Relevant part (hopefully):
