No, growing a vector (which push_back can do) invalidates all references

Would building with --enable-dbgutil on Linux (thus defining
_GLIBCXX_DEBUG) had caught this problem?

no, because there's no iterator involved: back() returns a reference to
the value_type.

If yes, they I certainly start agreeing with you (IIRC) that
developers should use --enable-dbgutil.

despite not helping here, _GLIBCXX_DEBUG finds sufficiently many
problems already that i think it's definitely worth using.
