[Debian-med-packaging] Bug#1015476: libbpp-qt: ftbfs with LTO (link time optimization) enabled

[Steve Langasek]

Package: libbpp-qt
Version: 2.4.1-9.1
Followup-For: Bug #1015476
User: ubuntu-devel at lists.ubuntu.com
Usertags: origin-ubuntu noble ubuntu-patch
Control: tags -1 patch

Dear maintainers,

This build failure is reproducible in Ubuntu, where LTO is enabled by
default on amd64.  The attached patch was sufficient to fix the build
failure there, and I expect will be sufficient to fix it in Debian with LTO
enabled, as well.

Thanks for considering,
