non-virtual thunk in Carbon Databrowser: always a crash?

i'm getting a slew of crash reports, all of them crashing while the databrowser is just doing it's thing.

seems they ALL have "non-virtual thunk" in the call stack, which i understand relates to a v-table not working?  but this is in apple code.

what can i do?

is there a C++ xcode setting i can tweak?

before you go there:
converting to cocoa is not an option

thanks!
