Comment (by kencu):

 This error is generally caused by a conflict between different versions of
 libstdc++.dylib. The one installed by the gcc ports and the one installed
 by the system interact in an unfavourable way, where objects are created
 by one version and attempt to be released by the other. The fact that it
 disappeared later on with gcc changes is more-or-less just luck.

 There are two known fixes so far.

 1. use {{{DYLD_LIBRARY_PATH}}} set to the macports-installed
 libstdc++.dylib location (currently {{{${prefix}/lib/libgcc}}}
 2. replace the system's {{{/usr/lib/libstdc++.dylib}}} with the current
 one being used, or at least a much newer one.

 The first option is obviously much simpler, but relies on setting that env
 var all the time, either in binary wrappers or in the {{{.profile}}}.

 The second option is tempting -- we are discussing this with the gcc leads
 -- but it is bound to cause concerns, and it is difficult to test out
 every possible existing executable that is linked to the current version,
 so realistically, this is likely to never happen.
