[Debian-med-packaging] Bug#1050164: libleidenalg: missing symbols with newer glibc/lto

[Gianfranco Costamagna]

Package: libleidenalg
Version: 0.11.1-1
Severity: normal
Tags: patch


Dear Maintainer,
I found in Ubuntu that 4 symbols are disappearing, probably due to lto and them being virtually provided.
I think it might be useful to mark them as optional, to avoid FTBFS with lto or newer gcc versions.

Thanks for considering the patch.
