After uninstalling the installed version (dev-db/mysql++-3.2.1) all went fine, which proves that it was linking against the "system" library instead of the one it had just compiled.

[Comment 2 Jeroen Roovers (RETIRED) 2017-10-25 14:28:39 UTC]

The problems seems to be caused in part by the LDFLAGS related changes in files/mysql++-3.0-gcc-as-needed.patch

[Comment 3 Jeroen Roovers (RETIRED) 2017-10-25 14:58:35 UTC]

Fixed in 3.2.3 without revision bump.
