I think it's actually because the actual library in question is
liboctinterp.so and thus not in the main executable, which is only
linked to that library. This warning happens for pretty much all
breakpoints except any you set in main.cc.

Once the library is loaded (e.g. by running int main()), future
warnings don't appear anymore.
