Hello,
I am a user who pinned this package to version 2.9.15-4, because of
this bug.
I took a look at the bug log, but I am afraid I did not understand the
conclusion: is there an actual ABI break or is it just some weak
symbols appearing/disappearing depending on different inlining
decisions taken by different compiler versions?

Will libreoffice/1:5.4.1-1 (currently in unstable and testing) break,
if I upgrade coinor-libcoinutils3v5 from version 2.9.15-4 to version
2.10.14+repack1-1 ?

Should this bug report be closed or kept open?

Could you please clarify?
Thanks for your time and patience!
