It looks like connection_base::RemoveTrigger() is failing. I guess we
have R.second = R.first = m_Triggers.end(), in which case this line:
const TriggerList::iterator i = find(R.first, R.second, E);
may fail in some implementations, but definitely this one:
if (m_Conn && (R.second == ++R.first))
Exec(("UNLISTEN \"" + T->name() + "\"").c_str(), 0);
Jeroen? Any idea if this can ever happen?
Cheers,
Bart
