Comment (by kencu):

 Oh, that's too bad. That error is the one we usually see when there is an
 ABI mismatch between the system libstdc++ and the libstdc++ installed by
 the libgcc port.

 That error did not happen with gcc 7.4.0 but does sometimes with gcc 7.5.0
 and newer.

 We have a workaround that we use to "wrap" the binaries and force the
 libstdc++ we need, but that will take some time to get sorted out, I'm
 afraid. The wrapping mechanism is part of the legacysupport-1.0 PortGroup
 if you feel enthusiastic :>

 I'll get to is (or somebody will) in due course.
