Comment 9 for bug 1939413

The rebuild of protobuf no longer has lto information according to objdump, but the reported version certainly does. The "bad" version was built during hirsute devel, so I took a current hirsute system and systematically downgraded build-deps to the versions in the log of the "bad" build. Turns out, the relevant difference is a couple libs from elfutils: libdw1 and libelf1. If I build protobuf w/ the 0.183-6 versions, I can reproduce the problem. 0.183-8 does not (0.183-7 FTBFS, so could not be tested).

Strangely the delta between elfutils 0.183-6 and 0.183-8 appears innocuous - it all looks like packaging cleanup, no changes to upstream source.
