$ mongo
mongo: symbol lookup error: mongo: undefined symbol: _ZN4YAML6detail9node_data12empty_scalarB5cxx11E

Downgrading to yaml-cpp-0.6.2 works. Probably rebuilding mongodb (with yaml-cpp-0.6.3) will work too, but can't wait for that now. 

See also https://bugs.gentoo.org/604166 in which this is claimed to be fixed with https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=4dea10267a05a8b51303a6a18920441175577711

A similar dependency is still in recent ebuilds, but mongodb was not auto-rebuilt on my system when yaml-cpp was upstepped.




Reproducible: Always

Yaml-cpp 0.6.2 and 0.6.3 both have the same subslot so portage didn't rebuild mongodb.
Comment 2 Tomáš Mózes 2020-01-07 23:23:44 UTC 
So it seems like there is an API breakage in yaml-cpp which got fixed in 0.6.3-r1. Can you please test that one instead please?

Test OK. Tested with the available yaml-cpp versions, mongodb-4.2.2 was not rebuilt (identical subslot) but both versions worked fine.
